     BACKGROUND OF THE INVENTION 
     This invention is drawn to novel fungicides. 
     With the world more dependent for food on an ever decreasing amount of cultivated farmland, it is increasingly important to develop effective fungicides which protect crops from fungicidal destruction. 
     Kozlik et al, in CA 79:53327Z, disclosed 1-carbamolyimidazoles as insecticidal. 
     Brookes et al, in U.S. Pat. Nos. 4,080,462 and 3,991,071, disclosed 1-(N,N-disubstituted carbamoyl and thiocarbamoyl)-imidazoles as fungicidal.

     DETAILED DESCRIPTION OF THE INVENTION 
     The compounds of the present invention wherein X is oxygen or sulfur and alk is not an α-branched-chain alkylene group are conveniently prepared according to the following synthetic scheme: ##STR12## wherein R, R 1 , R 2  and alk are as defined above; W is a halogen, b is a base, b 2  is an acid scavenger (a base), Rd is a reducing agent and A is an alkylene group 1 carbon shorter in length than the resulting alk group. 
     Reaction (1) is conducted by adding approximately 2 equivalents of a base, IV, to II. The reaction is done in the liquid phase employing an organic solvent such as ethanol, methanol, and the like, or alternatively water. Preferably, the base employed is an inorganic base. Suitable inorganic bases include, for instance, sodium hydride, sodium methoxide, metallic sodium, and the like. After addition of IV, an approximately equimolar amount of III is added to the system. Reaction pressure is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. The reaction is generally conducted at from 0° C. to 100° C., although preferably at from 40° C. to 70° C., and is generally complete from within 1 to 48 hours. The resulting intermediate, V, is isolated by conventional procedures such as extraction, filtration, chromatography, distillation, or alternatively, used in Reaction (2) without purification and/or isolation. 
     Reaction (2) is conducted by adding an essentially equimolar amount of carbonyldiimidazole, VI, to V. The reaction is conducted in the liquid phase using an inert anhydrous organic solvent such as chloroform, methylene chloride, dimethoxyethane, toluene, and the like. Reaction pressure is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. The reaction is generally conducted at from 0° C. to 100° C., although preferably at room temperature, and is generally complete from within 1 to 24 hours. The resulting carboxylic acid imidazolide, VII, may be isolated by conventional procedures such as extraction, filtration, chromatography, distillation, and the like. Alternatively and preferably, the resulting intermediate is not isolated from the reaction solution, but is used directly in Reaction (3). 
     Reaction (3) is conducted by adding an essentially equimolar amount of the appropriate primary amine, VIII, to VII. The reaction is conducted in the liquid phase using an inert anhydrous organic solvent such as chloroform, methylene chloride, dimethoxyethane, toluene, and the like. Preferably, the reaction solution is the same as was employed in Reaction (2) with the appropriate amine, VIII, merely added to the system after completion of Reaction (2). Reaction pressure is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. The reaction is generally conducted at from 0° C. to 100° C., although preferably at room temperature, and is generally complete from within 1 to 24 hours. The resulting amide, IX, is isolated by conventional procedures such as extraction, filtration, chromatography, distillation, or alternatively, used in Reaction (4) without purification and/or isolation. 
     Alternatively, IX may be prepared according to Reaction (2a-3a) by adding a solution of the acid chloride corresponding to V to a solution of VIII. The acid chloride Va is prepared from the acid V by techniques known to the art, such as treatment with thionyl chloride. The reaction is conducted in the presence of b 2  (IVa), an acid scavenger such as triethylamine, pyridine, an alkylamine, sodium carbonate, or the like. The reaction is conducted in the liquid phase using an inert organic solvent such as methylene chloride, chloroform, dioxane, toluene, and the like. The reaction is carried out at a temperature of about -50° C. to about 100° C., preferably from about 0° C. to about 25° C. After the addition is complete, the reaction mixture is allowed to return to room temperature. The reaction is generally complete within about 0 to about 48 hours after the addition is complete. The resulting amide IX is isolated by conventional procedures such as extraction, filtration, chromatography, distillation, or alternatively used in Reaction (4) without further purification or isolation. 
     Reaction (4) is a conventional reduction of the amide to the amine. 
     In preparing compounds of this invention, the carbonyl of the amide is reduced to the methylene group; the reaction is conveniently conducted by adding an essentially equimolar amount of a reducing agent, Rd, to IX. The reaction is conducted in the liquid phase employing an inert anhydrous organic solvent such as toluene, benzene, and the like. Suitable reducing agents include, for instance, lithium aluminum hydride, borane, borane methyl sulfide, and the like. Preferably, due to the ease in handling the reagent, borane methyl sulfide is employed as the reducing agent. However, when R 1  is a group susceptible to an undesired reaction with borane or borane methyl sulfide (such as allyl, propargyl, and the like), the preferred reducing agent is lithium aluminum hydride. Reaction pressure is not critical and for convenience, the reaction is conducted at atmospheric pressure. The reaction is generally conducted at from 0° C. to 110° C., although preferably at from 30° C. to 70° C., and is generally complete from within 1 to 24 hours. The resulting amine, XI, is isolated by conventional procedures such as extraction, filtration, chromatography, distillation, or alternatively, used in Reaction (5) without purification and/or isolation. 
     Reaction (5) is conducted by first preparing reagent XII. XII is prepared by adding an essentially equimolar amount of carbonyldiimidazole to the appropriate acid, R 2  CO 2  H wherein R 2  is as defined above. The reaction is conducted in the liquid phase using an inert anhydrous organic solvent such as chloroform, methylene chloride, dimethoxyethane, toluene, and the like. Reaction pressure is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. The reaction is generally conducted at from 0° C. to 100° C., although preferably at room temperature, and is generally complete from within 1 to 24 hours. The resulting reagent, XII, may be isolated by conventional procedures such as extraction, filtration, chromatography, distillation, and the like. Alternatively and preferably, the reagent is not isolated from the reaction solution but an essentially equimolar amount of the amine, XI, is added to the system. Reaction pressure for this reaction is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. After addition of XI, the reaction is generally conducted at room temperature and is generally complete from within  1 to 24 hours. The product, Ia, is then isolated by conventional procedures such as extraction, filtration, chromatography, distillation, or alternatively, used in Reaction (6) without purification and/or isolation. 
     Alternatively, product Ia may be prepared by Reaction (5a) using the acid chloride XIII corresponding to R 2  CO 2  H. Acid chloride XIII may be conveniently prepared by combining approximately equimolar amounts of R 2  CO 2  H and thionyl chloride. The reaction is conducted in the liquid phase using an inert organic solvent such as methylene chloride, toluene, chloroform, and the like. It is preferred to conduct the reaction in the presence of a catalytic amount of dimethylformamide. The reaction mixture is heated to reflux and refluxed for about 0 to about 24 hours. The mixture is stirred until gas evolution ceases. After the temperature of the mixture returns to room temperature, XIII may be used in Reaction (5a) without purification or isolation. Since XIII is susceptible to hydrolysis, minimal handling of it is preferred. 
     Reaction (5a) is conducted by combining XIII, with XI and IVa. The reaction is conducted in the liquid phase using an inert organic solvent such as methylene chloride, chloroform, toluene and the like. Suitable acid scavengers, b 2  (IVa), include bases such as triethylamine, pyridine, an alkylamine, sodium carbonate, and the like. The reaction is carried out at a temperature of about -25° C. to about 100° C., preferably from about 0° C. to about 25° C., and may be conveniently carried out at room temperature. The reaction is generally complete within about 0 to about 24 hours. Product Ia is then isolated by conventional procedures such as extraction, filtration, chromatography, distillation, or alternatively, used in Reaction (6) without purification and/or isolation. 
     Reaction (6) is conducted by adding an essentially equimolar amount of phosphorus pentasulfide, XIII, to I. The reaction is conducted in the liquid phase using an inert anhydrous organic solvent such as toluene, tetrahydrofuran, and the like. Preferably, the system is exposed to microwave radiation in order to facilitate the dispersion of phosphorus pentasulfide into solution. Reaction pressure is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. The reaction is generally conducted at from 15° C. to 100° C., although preferably it is conducted at the ambient temperature and is generally complete from within 1 to 48 hours. The product is then isolated by conventional procedures such as extraction, filtration, chromatography, distillation, and the like. 
     The compounds of this invention wherein X is oxygen or sulfur and alk is an α-branched-chain alkylene group are conveniently prepared according to the following synthetic scheme: ##STR13## wherein R and R 1  and b are as defined above; W is a halogen; Ac is an acid; U is an alkylene group and T is an alkyl group such that the sum of the number of carbon atoms in U and T is one carbon less than the number in alk; and Rd 2  is a reducing agent. 
     Reaction (7) is conducted by adding approximately equimolar amounts of II and XV to IV in solvent. The reaction is done in the liquid phase employing an organic solvent such as ethanol, methanol, and the like. Preferably, the base employed is an inorganic base. Suitable inorganic bases include, for instance, sodium hydride, sodium methoxide, metallic sodium, and the like. Reaction pressure is not critical and for convenience, the reaction is generally conducted at atmospheric pressure. The reaction is generally conducted at from about 25° C. to about 100° C., although preferably at from about 60° C. to about 78° C., and is generally complete within about 2 to about 48 hours. The resulting intermediate, XV is isolated by conventional procedures such as extraction, filtration, chromatography, or distillation. 
     Reaction (8) is conducted by adding an excess of VIII and XVII to a stirred mixture of XV in solvent. The reaction is conducted in the liquid phase employing an inert anhydrous organic solvent such as methanol, ethanol, acetonitrile, and the like. Suitable reducing agents include those which are relatively mild and selective and include for instance, sodium cyanoborohydride, sodium borohydride, and the like. The preferred reducing agent is sodium cyanoborohydride. After the addition is complete, the system is acidified to a pH of about 5 to 6 using acid XVIII, preferably a non-aqueous acid such as hydrogen chloride gas. The reaction is generally conducted at from about 0° C. to about 50° C., and for convenience, it may be conducted at ambient temperature. The reaction is generally complete within about 1 to about 24 hours. The resulting amine XIa may be isolated by conventional procedures such as extraction, filtration, chromatography, and the like, or used without purification and/or isolation is Reaction (5). 
     The amine XIa is then converted to the compounds of this invention as outlined in Reactions (5) and (6). 
     The compounds of this invention wherein X represents a direct linkage between alk and R are conveniently prepared by starting with the appropriate reagent V and following Reactions (2) through (6). 
     Alternatively, these compounds may be prepared from the appropriate 3-phenyl, 3-substituted phenyl, or α- and/or β-substituted cinnamic acid as the starting material for Reaction (2). Reaction (3) is then conducted as above. However, in Reaction (4), an additional equivalent of boron methyl sulfide is required in order to saturate the vinylic group. After Reaction (4), the synthesis is accomplished through Reactions (5) and (6) as described above. 
     UTILITY 
     The compounds of the invention are effective in controlling fungal infections. Some of the compounds of this invention are particularly effective in controlling powdery mildew fungal infections caused by the organism Erysiphe polygoni. Some of the compounds of this invention are also useful for controlling leaf blights caused by organisms such as Phytophthora infestans conidia, Alternaria solani conidia, and Septoria apii. Some of the compounds of this invention are also useful for controlling fungal infections caused by Uromyces phaseoli tipica, Plasmopara viticola, and Piricularia oryzae. However, some fungicidal compounds of this invention may be more fungicidally active than others against particular fungi. 
     When used as fungicides, the compounds of the invention are applied in fungicidally effective amounts to fungi and/or their habitats, such as vegetative hosts and non-vegetative hosts, e.g., animal products. The amount used will, of course, depend on several factors such as the host, the type of fungus, and the particular compound of the invention. As with most pesticidal compounds, the fungicides of the invention are not usually applied full strength, but are generally incorporated with conventional, biologically inert extenders or carriers normally employed for facilitating dispersion of active fungicidal compounds, recognizing that the formulation and mode of application may affect the activity of the fungicide. Thus, the fungicides of the invention may be formulated and applied as granules, as powdery dusts, as wettable powders, as emulsifiable concentrates, as solutions, or as any of several other known types of formulations, depending on the desired mode of application. 
     Wettable powders are in the form of finely divided particles which disperse readily in water or other dispersants. These compositions normally contain from about 5% to 80% fungicide, and the rest inert material, which includes dispersing agents, emulsifying agents and wetting agents. The powder may be applied to the soil as a dry dust, or preferably as a suspension in water. Typical carriers include fuller&#39;s earth, kaolin clays, silicas, and other highly absorbent, readily wettable, inorganic diluents. Typical wetting, dispersing or emulsifying agents include, for example: the aryl and alkylaryl sulfonates and their sodium salts; alkylamide sulfonates, including fatty methyl taurides; alkylaryl polyether alcohols, sulfated higher alcohols and polyvinyl alcohols; polyethylene oxides; sulfonated animal and vegetable oils; sulfonated petroleum oils; fatty acid esters of polyhydric alcohols and the ethylene oxide addition products of such esters; and the addition products of long-chain mercaptans and ethylene oxide. Many other types of useful surface-active agents are available in commerce. The surface-active agent, when used, normally comprises from 1% to 15% by weight of the fungicidal composition. 
     Dusts are freely flowing admixtures of the active fungicide with finely divided solids such as talc, natural clays, kieselguhr, pyrophyllite, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulfur, lime, flours, and other organic and inorganic solids which act as dispersants and carriers for the toxicant. These finely divided solids have an average particle size of less than about 50 microns. A typical dust formulation useful herein contains 75% silica and 25% of toxicant. 
     Useful liquid concentrates include the emulsifiable concentrates, which are homogeneous liquid or paste compositions which are readily dispersed in water or other dispersant, and may consist entirely of the fungicide with a liquid or solid emulsifying agent, or may also contain a liquid carrier such as xylene, heavy aromatic naphthas, isophorone, and other nonvolatile organic solvents. For application, these concentrates are dispersed in water or other liquid carrier, and are normally applied as a spray to the area to be treated. 
     Other useful formulations for fungicidal applications include simple solutions of the active fungicide in a dispersant in which it is completely soluble at the desired concentration, such as acetone, alkylated naphthalenes, xylene, or other organic solvents. Granular formulations, wherein the fungicide is carried on relatively coarse particles, are of particular utility for aerial distribution or for penetration of cover-crop canopy. Pressurized sprays, typically aerosols wherein the active ingredient is dispersed in finely divided form as a result of vaporization of a low-boiling dispersant solvent carrier, such as the Freons, may also be used. All of those techniques for formulating and applying fungicides are well known in the art. 
     The percentages by weight of the fungicide may vary according to the manner in which the composition is to be applied and the particular type of formulation, but in general comprise 0.5% to 95% of the toxicant by weight of the fungicidal composition. 
     The fungicidal compositions may be formulated and applied with other active ingredients, including other fungicides, insecticides, nematocides, bactericides, plant-growth regulators, fertilizers, etc. 
     A further understanding of the invention can be had in the following non-limiting Examples. Wherein, unless expressly stated to the contrary, all temperature ranges refer to the Centigrade system and the term &#34;ambient&#34; or &#34;room temperature&#34; refers to about 20° C. to 25° C. The term &#34;percent&#34; refers to gram moles. The term &#34;equivalent&#34; refers to a quantity of reagent equal in moles, to the moles of the preceding or succeeding reagent recited in that example in terms of finite moles or finite weight or volume. Also, unless expressly stated to the contrary, geometric isomer and racemic mixtures are used as starting materials and correspondingly, isomer mixtures are obtained as products. 
    
    
     Compounds which were prepared in accordance with Examples 1 through 22 below are found in Tables I to IV. 
     EXAMPLES 
     Example 1 
     Preparation of 2,4,6-trichlorophenoxyacetic acid 
     2,4,6-trichlorophenol, 100.7 gm, was added to 250 ml of ethanol. 228.6 ml of a 25% solution of sodium methoxide (2 equivalents) in methanol was then added to the system. The system was stirred at room temperature for approximately 1 hour. Afterwards, 69.5 gm of bromoacetic acid was added an the system then heated to reflux. After 18 hours, an additional equivalent of sodium methoxide in methanol (114.3 ml) was added as well as 34.7 gm of bromoacetic acid. The system was continued at reflux for 12 hours. The reaction was then stopped and the solvent removed by stripping. The resulting solid was washed with water and then with ether. Concentrated HCl was next added to the solid precipitate and the system was left standing for 12 hours. Afterwards, the product was filtered, washed with water and air dried. Toluene was then added to the product. The toluene was removed by stripping and any remaining water was azeotroped off with the toluene. 74.4 gm of 2,4,6-trichlorophenoxyacetic acid was recovered. 
      Example 2 
     Preparation of N-(n-propyl)-2,4,6-trichlorophenoxyacetamide 
     (a) 2,4,6-trichlorophenoxyacetic acid, 47.5 gm, was added to 300 ml of methylene chloride along with 30.3 gm of carbonyldiimidazole. The system was stirred overnight to give the carboxylic acid imidazolide. 
     (b) 15.4 ml of n-propylamine was then added to the system. The system was then stirred at room temperature for an additional 20 hours. The reaction was stopped and the organic solution was washed first with a dilute HCl solution, then with a sodium bicarbonate solution and then with water. The methylene chloride was removed by stripping to give the N-(n-propyl)-2,4,6-trichlorophenoxyacetamide. 
     Example 2a 
     Preparation of N-(n-propyl)-2,4,6-trichlorophenoxyacetamide 
     A solution of 2625 gm (9.62 moles) 2,4,6-trichlorophenoxyacetic acid chloride in methylene chloride (total solution weight 5403 gm) was added to a solution of 1251 gm (21.17 moles) n-propylamine in 7.6 methylene chloride in a 22-liter flask over a period of 2 hours. During the addition, the temperature of the system was maintained at about 5° C. to 7° C. using a dry ice/isopropyl alcohol bath. During the addition, some white solids precipitated. After the addition was complete, the cooling bath was removed allowing the temperature of the system to rise to 10° C. over 25 minutes. The system temperature was then raised to 23° C. over 10 minutes by use of a warm water bath. Sample NMR and IR spectra indicate the reaction was complete. After removal of the warming bath, the methylene chloride solution was washed 3 times with 4 water. The aqueous layer and organic layers were separated and the organic phase was dried over 150  gm magnesium sulfate. The organic solution was stripped until the weight reached about 3 kg. While the system was still in the hot water bath, 3.5 hexane was added, giving a clear solution. The system was then cooled to 20° C., giving a very thick slurry of crystals. The crystals were filtered and washed with 2 hexane. Air drying gave 2102 gm. 
     The mother liquor and hexane washings were stripped to give 450 gm of a brown oil which solidified upon cooling. Recrystallization from hexane (about 900 ml), followed by filtering the crystals, washing the crystals with hexane (about 500 ml), and air drying gave an additional 342 gm of the product. 
     Example 3 
     Preparation of N-(n-propyl) ethanolamine 2,4,6-trichlorophenylether 
     N-(n-propyl)-2,4,6-trichlorophenoxyacetamide, 44.0 gm, was added to 250 ml of toluene. 28 ml of borane methyl sulfide [BH 3 .(CH 3 ) 2  S] (2 equivalents) was then slowly added to the system. The system was heated at approximately 60° C. for 15 hours at which time reaction completion was checked by IR spectroscopy. 200 ml of methanol was then slowly added to the system. After addition of the methanol, the system was acidified by bubbling in HCl gas. Afterwards, the system was refluxed for 1 hour. The solvent was then removed by stripping. The resulting oil was dissolved in methanol which was then stripped. The oil was next dissolved in methylene chloride. The organic solution was washed with a sodium hydroxide solution and then with water. The methylene chloride was removed by stripping to give 36.3 gm of the N-(n-propyl) ethanolamine 2,4,6-trichlorophenylether, as a yellow oil.

     Tomato Late Blight 
     Compounds of the invention were tested for the preventative control of the Tomato Late Blight organism Phytophthora infestans. Five- to six-week-old tomato (cultivar Bonny Best) seedlings were used. The tomato plants were sprayed with a 250-ppm suspension of the test compound in acetone, water and a nonionic emulsifier. The sprayed plants were then inoculated 1 day later with the organism, placed in an environmental chamber and incubated at 66° F. to 68° F. and 100% relative humidity for at least 16 hours. Following the incubation, the plants were maintained in a greenhouse for approximately 7 days. The percent disease control provided by a given test compound was based on the percent disease reduction relative to untreated check plants. The results are tabulated in Table V. 
     Example C 
     Celery Late Blight 
     The Celery Late Blight tests were conducted using celery (Utah) plants 11 weeks old. The Celery Late Blight organism was Septoria apii. The celery plants were sprayed with 250-ppm solutions of the candidate toxicant mixed with acetone, water and a nonionic emulsifier. The plants were then inoculated with the organism and placed in an environmental chamber and incubated at 66° F. to 68° F. in 100% relative humidity for an extended period of time (approximately 48 hours). Following the incubation, the plants were allowed to dry and then were maintained in a greenhouse for approximately 14 days. The percent disease control provided by a given candidate toxicant is based on the percent disease reduction relative to untreated check plants. The results are reported in Table V. 
     Example D 
     Tomato Early Blight 
     Compounds of the invention were tested for the control of the Tomato Early Blight organism Alternaria solani conidia. Tomato (variety Bonny Best) seedlings of 6- to 7-weeks old were used. The tomato plants were sprayed with a 250-ppm solution of the test compound in an acetone-and-water solution containing a small amount of a nonionic emulsifier. The sprayed plants were inoculated 1 day later with the organism, placed in the environmental chamber and incubated at 66° F. to 68° F. and 100% relative humidity for 24 hours. Following the incubation, the plants were maintained in a greenhouse for about 12 days. Percent disease control was based on the percent disease development on untreated check plants. The compounds tested and the results are tabulated in Table V. 
     Example E 
     Grape Downy Mildew 
     The compounds of the invention were tested for the control of the Grape Downy Mildew organism Plasmopara viticola. Detached leaves, between 70 mm and 85 mm in diameter, 7-week-old Vitis vinifera cultivar Emperor grape seedlings were used as hosts. The leaves were sprayed with a 250-ppm solution of the test compound in acetone. The sprayed leaves were dried, inoculated with a spore suspension of the organism, placed in a humid environmental chamber and incubated at 66° F. to 68° F. and about 100% relative humidity. After incubation for 2 days, the plants were then held in a greenhouse 7 to 9 days; then the amount of disease control was determined. The percent disease control provided by a given test compound was based on the percent disease reduction relative to untreated check plants. The results are tabulated in Table V. 
     Example F 
     Leaf Rust 
     The Leaf Rust test was made using pinto beans. The pathogen was Uromyces phaseoli tipica. The pinto bean plants were sprayed with a 250-ppm solution of the test compound in an acetone-water mixture containing a nonionic emulsifier. The treated plants were inoculated thereafter with the pathogen and then incubated in an environmental chamber for approximately 20 hours at 100% relative humidity and a temperature of 68° F. to 70° F. The plants were then removed from the chamber, allowed to dry, and then maintained in a greenhouse at a 60% to 80% relative humidity. The rate of infection on the leaves was made after about 14 days. The percent disease control provided by a given test compound was based on the percent disease reduction relative to untreated check plants. The results are reported in Table V. 
     Example G 
     Rice Blast 
     Compounds of this invention were tested for control of the Rice Blast organism Piricularia oryzae, using 10- to 14-day-old rice plant seedlings (Calrose M-9 variety). Seedling plants were sprayed with a 625-ppm solution of the test compound in acetone, water and a non-ionic emulsifier (ORTHO X-77 spreader). The sprayed plants were inoculated 1 day later with the organism in an environmental chamber. After inoculation, the plants were kept in an environmental chamber for about 48 hours under conditions of about 72° F. to 75° F. and about 100% relative humidity. Following the incubation period, the plants were placed in a greenhouse with a temperature of about 72° F. and maintained with bottom watering for about 12 to 16 days. The percent disease control provided by a given test compound is based on a comparison of the percentage disease relative to the percent disease development on the untreated check plants: ##EQU1## The results are tabulated in Table V.
