Combating pests with benzyl phenyl ethers
This is a division of application Ser. No. 809,492, filed June 23, 1977, now U.S. Pat. No. 4,145,439. 
    
    
     The present invention relates to the use as pesticides of certain substituted benzyl phenyl ethers, some of which are known. 
     Pesticides are to be understood, in the present context, as agents which are suitable for combatting animal pests as well as phytopathogenic fungi and bacteria. 
     It has already been disclosed to use synthetic juvenile hormones, such as isopropyl-(2 E, 4 E)-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate, for combatting harmful insects. However, these compounds are obtainable only by means of involved and expensive syntheses. Furthermore, they are stable for only a short time when exposed to light and air. In addition, they are not suitable for combatting insects that cause the greatest damage in the larva stage, since they only become effective when the imago develops from the larva stage. 
     It has further been disclosed in German Published Specification DOS 2,418,343 to use diphenyl ether derivatives for combatting harmful insects. However, the action of these compounds is not satisfactory, especially if low concentrations are used. 
     It has now been found that the substituted benzyl phenyl ethers of the general formula ##STR3## in which X is ##STR4## R 1  is H or alkyl, R 2  is alkyl, alkenyl, alkynyl, alkylidene, alkenylidene or alkynylidene optionally substituted by OH, alkoxy, a heterocyclic group containing O, S or N, amino, monoalkylamino, dialkylamino or by an alkylene bridge with 5 carbon atoms, 
     R 3  each independently is H, alkyl, alkoxy, alkylmercapto, halogen, halogenoalkyl, halogenoalkoxy, halogenoalkylmercapto, NO 2 , amino, monoalkylamino or dialkylamino, 
     R 4  each independently is H, halogen or alkoxy, 
     m is an integer from 1 to 5, and 
     n is an integer from 1 to 4, 
     and salts thereof exhibit powerful pesticidal, i.e. athropodicidal, nematicidal, fungicidal and bactericidal properties. 
     Salts with inorganic acids, such as HCl, HBr, HI, H 2  SO 4 , H 3  PO 4 , or with organic acids, such as formic acid, acetic acid, oxalic acid, sorbic acid or citric acid, are also suitable for use as pesticides. 
     Some of the active compounds of the general formula (I) are known from U.S. Patent No. 2,676,173, German Offenlegungsschrift (German Published Specification) 2,364,191 and Tetrahedron Letters 1974 (26), 2261-4. 
     Some of the active compounds according to the invention are new and can, like the known compounds, be prepared by hydrogenating Schiff&#39;s bases of the general formula ##STR5## in which R 1 , R 3 , R 4 , m and n have the above-mentioned meanings and 
     R 2  is alkyl or alkylidene with 4-18 carbon atoms, alkenyl or alkenylidene with 3-8 carbon atoms or alkynyl or alkynylidene with 3-8 carbon atoms, each optionally substituted by an alkoxy radical with 1-6 carbon atoms as well as by OH, amino, monoalkylamino or dialkylamino with 1-6 carbon atoms in each alkyl moiety, an alkylene bridge with 5 carbon atoms, or furfuryl of the formula ##STR6## and, if R 3  is not H, R 2  can, in addition to the above-mentioned meanings, be optionally substituted C 1-3  alkyl. 
     The new compounds are defined by the general formula ##STR7## in which X, R 2 , R 3 , R 4 , n and m have the meanings mentioned in connection with formulae (II) and (III). 
     The course of the reaction by which the new active compounds according to the invention are prepared can be illustrated by the following equation for the case of [4-(4-methylbenzyloxy)-benzylidene]-3-ethoxypropylamine and NaBH 4  serving as starting materials. ##STR8## 
     The hydrogenation can be carried out either with hydrogen under pressure in the presence of a suitable catalyst, such as Raney nickel, palladium or platinum, or with hydrogenating agents such as NaBH 4  or LiAlH 4 , or with formic acid in the presence of a suitable diluent. In every case, the carbonyl compounds and amines from which the Schiff&#39;s bases of the formula (II) or (III) are formed can also be used as the starting materials directly, without intermediate isolation of the Schiff&#39;s bases. 
     The preparation of the active compounds of the formula (I) in which X represents the group ##STR9## and of the new compounds of the formula (IV), can be carried out by catalytic hydrogenation of the corresponding Schiff&#39;s bases. Suitable diluents for the catalytic reduction of the Schiff&#39;s bases of the general formula (II) or (III) are all inert organic solvents, such as cyclohexane, benzine, benzene, toluene and xylene, and also alcohols, such as methanol, ethanol and isopropyl alcohol. 
     Examples of catalysts which can be used are Pd, Pt or Raney nickel. 
     The reaction temperatures can be varied within a fairly wide range. In general, the reaction is carried out at from 50° to 150° C., preferably at from 80° to 120° C. 
     The reaction is generally carried out at pressures of 60-150 bars, preferably of 80-120 bars. 
     Alternatively, the carbonyl compounds from which the Schiff&#39;s bases of the formula (II) or (III) are formed, together with the corresponding primary amines, can be reduced catalytically under the same conditions with hydrogen under pressure, while heating, to give the corresponding amines. 
     Hydrogenating agents which can be used are complex hydrides for example LiAlH 4 , NaBH 4 , KBH 4 , Na(OCH 3 ) 3  BH, LiBH 4  and NaBH 4 , and AlCl 3 . Suitable diluents for the hydrogenation with complex hydrides are all inert organic solvents, such as benzine, cyclohexane, toluene, xylene, or ethers such as diethyl ether, diisopropyl ether, 1,2-dimethoxyethane, dioxane or tetrahydrofuran, or mixtures of the stated solvents, for example ether/toluene. When using the less reactive hydrides such as, for example, NaBH 4 , alcohols such as methanol, ethanol, propanol and isopropyl alcohol, H 2  O, NH 3 , amines such as methylamine, ethylamine, isopropylamine, ethylenediamine, aniline, pyridine and morpholine, acetonitrile, methylene chloride, chloroform or dimethylformamide can also be employed. 
     The reaction temperatures can be varied within a fairly wide range. In general, the reaction is carried out at from 0° C. to the boiling point of the solvent used, preferably from 20° to 70° C. 
     The reaction can be carried out under normal pressure or elevated pressure. It is advantageous to work under normal pressure. 
     In carrying out the process according to the invention, 0.25 to 1 mole of the complex hydride is employed per mole of the Schiff&#39;s base. Advantageously, an excess of reducing agent is used. When using NaBH 4  in ethanol, it is preferred to use from 0.4 to 0.7 mole of NaBH 4  per mole of the Schiff&#39;s base. 
     Both the active compounds of the formula (I) in which X represents the group ##STR10## and the new compounds of the formula (IV), can be obtained by reduction of the corresponding Schiff&#39;s bases with formic acid. 
     The reaction can be carried out in the presence of a diluent; preferred diluents are inert organic solvents, for example hydrocarbons, such as benzene or toluene, and ethers such as diethyl ether. 
     The reducing agent used is 100% strength formic acid. The reaction temperatures can be varied within a fairly wide range. In general, the reaction is carried out at from 60° to 150°, preferably from 80° to the boiling point of the chosen solvent, up to 130° C. Usually, the reaction is carried out under normal pressure. 
     In carrying out the process according to the invention, it is preferred to use 2-5 moles of 100% strength formic acid per mole of Schiff&#39;s base. 
     In this reaction, again, it is alternatively possible directly to employ the amines and carbonyl compounds from which the Schiff&#39;s bases of the general formula (II) or (III) are formed.

     The preparation of the active compounds of the formula (I), in which X represents the group ##STR11## and of the new active compounds of the formula (IV), can also be carried out in accordance with the following processes (indicated only for the new active compounds), in which benzyl halides or tosylates of the general formula ##STR12## in which R 1 , R 3 , R 4 , m and n have the above-mentioned meanings and 
     Z represents halogen or the tolylsulphonyl radical, are reacted with ammonia or an amine, or in which amides of the general formula ##STR13## in which R 2 , R 3 , R 4 , m and n have the above-mentioned meanings, are reduced with hydrogen or a complex hydride. The latter process gives compounds of the general formula (I) or (IV) in which R 1  represents hydrogen. 
     Some of the Schiff&#39;s bases used for the preparation of the active compounds according to the invention are known. They can be prepared in accordance with methods which are in themselves known (see Houben-Weyl, Methoden der organischen Chemie (Methods of Organic Chemistry), Volume VII/1, year of publication 1954, pages 454-458, and Volume XI/2, year of publication 1958, pages 74-85). 
     The Schiff&#39;s bases of the formulae (II) and (III) are new. They are obtained by processes in which 
     (a) carbonyl compounds of the general formula ##STR14##  in which R 1 , R 3 , R 4 , n and m have the above-mentioned meanings, are reacted with amines of the general formula 
     
         R.sup.2 --NH.sub.2                                         (VIII), 
    
      in which 
     R 2  has the above-mentioned meaning, or in which 
     (b) amines of the general formula ##STR15##  in which R 1 , R 4 , R 3 , m and n have the above-mentioned meanings, are reacted with carbonyl compounds of the general formula 
     
         O═R.sup.2                                              (X), 
    
      in which 
     R 2  represents a doubly bonded radical having the above meaning. 
     These reactions can be carried out by heating the reactants without solvents, by heating in polar organic solvents such as alcohols or glacial acetic acid, or by heating in non-polar organic solvents such as toluene, xylene, cyclohexane and the like. These reactions can be catalysed by acids such as HCl or p-toluenesulphonic acid, by Lewis acids, such as ZnCl 2 , or by alkalis. It is frequently advantageous to distill off zeotropically the water formed during the reaction. 
     The reaction can be carried out under normal pressure or elevated pressure. 
     The compounds of the general formulae (II) and (III) can also be prepared by alkylating a Schiff&#39;s base of the general formula (XI) with an alkylating agent of the general formula (XII) in the presence of a base. This process can be represented by the following general equation: ##STR16## in which R 1 , R 2 , R 3 , R 4 , m and n have the above-mentioned meanings and 
     Y represents halogen (Cl, Br or I) or ##STR17## 
     Most of the carbonyl compounds of the formulae (VII) and (X) used for the preparation of the Schiff&#39;s bases are known; new compounds can be prepared in accordance with known processes (see Journ. Org. Chem. (1951) page 16 and page 85 et seq.). 
     As already mentioned, the active compounds of the formula (I) are outstandingly suitable for combating pests. Amongst them, the new compounds of the formula (IV) are particularly suitable. Furthermore, those compounds of the formula (IV) are preferred, 
     in which 
     X represents the radical ##STR18## R 2  represents straight-chain, branched , or cyclic alkyl or alkylidene with 4-18 carbon atoms, propenyl, propargyl, or pentynyl, any of which can optionally be substituted by an alkoxy radical with 1-4 carbon atoms, OH, dimethylamino or diethylamino or by an alkylene bridge with 5 carbon atoms, or R 2  represents furfuryl, and, if R 3  is not hydrogen, may also represent optionally substituted alkyl with 1-3 carbon atoms,

The following may be chiefly considered for use as conventional carrier vehicles for this purpose: aerosol propellants which are gaseous at normal temperatures and pressures, such as halogenated hydrocarbons, e.g. dichlorodifluoromethane and trichlorofluoromethane, as well as butane, propane, nitrogen and carbon dioxide; inert dispersible liquid diluent carriers, including inert organic solvents, such as aromatic hydrocarbons (e.g. benzene, toluene, xylene, alkyl naphthalenes, etc.), halogenated, especially chlorinated, aromatic hydrocarbons (e.g. chlorobenzenes, etc.), cycloalkanes, (e.g. cyclohexane, etc.), paraffins (e.g. petroleum or mineral oil fractions), chlorinated aliphatic hydrocarbons (e.g. methylene chloride, chloroethylenes, etc.), alcohols (e.g. methanol, ethanol, propanol, butanol, glycol, etc.) as well as ethers and esters thereof (e.g. glycol monomethyl ether, etc.), amines (e.g. ethanolamine, etc.), amides (e.g. dimethyl formamide, etc.), sulfoxides (e.g. dimethyl sulfoxide, etc.), acetonitrile, ketones (e.g. acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, etc.), and/or water; as solid carriers, ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly-dispersed silicic acid, alumina and silicates; as solid carriers for granules; crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, corn cobs and tobacco stalks; whereas the following may be chiefly considered for use as conventional carrier vehicle assistants, e.g. surface-active agents, for this prupose: emulsifying agents, such as non-ionic and/or anionic emulsifying agents (e.g. polyethylene oxide esters of fatty acids, polyethylene oxide ethers of fatty alcohols, alkyl sulfates, alkyl sulfonates, aryl sulfonates, albumin hydrolyzates, etc., and especially alkyl arylpolyglycol ethers, magnesium stearate, sodium oleate, etc.); and/or dispersing agents, such as lignin, sulfite waste liquors, methyl cellulose, etc. 
     Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, can be used in the formulations. 
     It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc. 
     Such active compounds may be employed alone or in the form of mixtures with one another and/or with such solid and/or liquid dispersible carrier vehicles and/or with other known compatible active agents, especially plant protection agents, such as other arthropodicides, nematicides, fungicides and bactericides, or rodenticides, herbicides, fertilizers, growth-regulating agents, etc., as illustratively outlined hereinabove, if desired, or in the form of particular dosage preparations for specific application made therefrom, such as solutions, emulsions, suspensions, powders, pastes, and granules which are thus ready for use. 
     As concerns commercially marketed preparations, these generally contemplate carrier composition mixtures in which the active compound is present in an amount substantially between about 0.1-95% by weight, and preferably 0.5-90% by weight, of the mixture, whereas carrier composition mixtures suitable for direct application or field application generally contemplate those in which the active compound is present in an amount substantially between about 0.0000001-100, preferably 0.01-10%, by weight of the mixture. Thus, the present invention contemplates overall compositions which comprise mixtures of a conventional dispersible carrier such as (1) a dispersible inert finely divided carrier solid, and/or (2) a dispersible carrier liquid such as an inert organic solvent and/or water, preferably including a surface-active effective amount of a carrier vehicle assistant, e.g. a surface-active agent, such as an emulsifying agent and/or a dispersing agent, and an amount of the active compound which is effective for the purpose in question and which is generally between about 0.0001-95%, and preferably 0.01-95%, by weight of the mixture. 
     The active compounds can also be used in accordance with the well known ultra-low-volume process with good success, i.e. by applying such compound if normally a liquid, or by applying a liquid composition containing the same, via very effective atomizing equipment, in finely divided form, e.g. average particle diameter of from 50-100 microns, or even less, i.e. mist form, for example by airplane crop spraying techniques. Only up to at most about a few liters/hectare are needed, and often amounts only up to about 15 to 1000 g/hectare, preferably 40 to 600 g/hectare, are sufficient. In this process it is possible to use highly concentrated liquid compositions with said liquid carrier vehicles containing from about 20 to about 95% by weight of the active compound or even the 100% active substance alone, e.g. about 20-100% by weight of the active compound. 
     Furthermore, the present invention contemplates methods of selectively killing, combating or controlling pests, e.g. arthropods, nematodes, fungi and bacteria, which comprises applying to at least one of correspondingly (a) such arthropods, (b) such nematodes, (c) such fungi, (d) such bacteria, and (e) the corresponding habitat thereof, i.e. the locus to be protected, e.g. to a growing crop, to an area where a crop is to be grown or to a domestic animal, a correspondingly combative or toxic amount, i.e. an arthropodicidally, nematicidally, fungicidally or bactericidally effective amount, of the particular active compound of the invention alone or together with a carrier vehicle as noted above. The instant formulations or compositions are applied in the usual manner, for instance by spraying, atomizing, vaporizing, scattering, dusting, watering, squirting, pouring, fumigating, and the like. 
     It will be realized, of course, that the concentration of the particular active compound utilized in admixture with the carrier vehicle will depend upon the intended application. Therefore, in special cases it is possible to go above or below the aforementioned concentration ranges. 
     The unexpected superiority and outstanding activity of the particular new compounds of the present invention are illustrated without limitation by the following experiments which show the insect growth regulation action, as well as the fungitoxic and bacteriotoxic action, of the compounds according to the invention; it is intended to imply a limitation in respect of the breadth of action of these compounds. 
     In the case of the experiments on the insect growth inhibition, the morphological changes, such as half-pupated animals, incompletely hatched larvae or caterpillars, defective wings or pupal cuticula in imagos, as well as the mortality, are assessed throughout the indicated development of the test insects. The sum of the morphological malformations and of the mortality during development is shown as a percentage of the number of test animals.
