This application is a division of Ser. No. 704,974, filed Feb. 25, 1985, U.S. Pat. No. 4,575,560, issued on Mar. 11, 1986. 
    
    
     The invention is diaminoguanidine hydrazone compounds of the formula (I) ##STR1## wherein R 1  &#39; and R 2  &#39; are H, and R 1  and R 2  are individually selected from fluoro, chloro, bromo, trifluoromethyl, CF 3  CH 2  O, CHF 2  X, CF 3  X, CHY 2  CF 2  X, or CHFYCF 2  X, where X is O or S and Y is F of Cl; or R 1  and R 1  &#39; or R 2  and R 2  &#39; are --OCF 2  O--, --OCF 2  CHFO--, --OC(CH 3 ) 2  --O-- or --OCF 2  CF 2  O--; 
     R is H, ##STR2## where R 3  is C 1  -C 2  alkyl, or C 1  -C 2  haloalkyl, R 4  is hydrogen or C 1  -C 2   alkyl; or R 3  and R 4  when taken together may form a ring represented by CH 2  (CH 2 ) n  -- where n is 3 or 4; R 5  is C 1  -C 4  alkyl optionally substituted with one to three halogens or C 3  -C 4  alkenyl, with the proviso that when R is ##STR3## R 1  and R 2  are CF 3  CH 2  O, CHF 2  X, CF 3  X, CHY 2  CF 2  X, or CHFYCF 2  S, where X is O or S and Y is F or Cl; R 1  and R 1  &#39; or R 2  and R 2  &#39; are --OCF 2  O--, --OC(CH 3 ) 2  --O--, --OCF 2  CHFO-- or --OCF 2  CF 2  O--. 
     While the use of diaminoguanidine compounds as antiprotozoal agents and especially as anticoccidial agents is known in the art as described in U.S. Pat. No. 3,992,446 and Belgian Pat. No. 824,811, there is no suggestion in the literature that diaminoguanidine hydrazone compounds are effective insecticidal agents or further that some of these compounds exhibit antifeeding activity when applied to plants. 
     The diaminoguanidine hydrazone compounds of the invention as well as other diaminoguanidine hydrazone compounds are effective in controlling lepidopterous insects and are useful for protecting agronomic crops, trees, shrubs, and ornamentals from attack by these insects. Many of these compounds also exhibit antifeeding activity thus providing additional protection to treated plants. 
     Novel formula (Ia) diaminoguanidine dialkyl ureas of the invention wherein R is ##STR4## in formula (I) may be readily prepared by the reaction of an appropriately substituted diaminoguanidine of formula (Ib) wherein R is H in formula (I) with from 1 to 2 molar equivalents of N,N-disubstituted carbamoyl chlorides of formula (III) in a solvent such as acetonitrile in the presence of a tertiary amine such as triethylamine or diisopropylethylamine as illustrated in Flow Diagram I below. ##STR5## wherein R 1 , R 1  &#39;, R 2 , R 2  &#39;, R 3  and R 4  are as described above. 
     Formula (Ia) diaminoguanidine monosubstituted ureas may be prepared by the reaction of the appropriately substituted formula (Ib) diaminoguanidine with from 1 to 1.5 molar equivalents of a formula (IV) isocyanate in an inert solvent such as ether as illustrated in Flow Diagram II below. ##STR6## wherein R 1 , R 1  &#39;, R 2 , R 2  &#39; and R 4  are as described above. 
     When R 1  and R 2  and R 1 , R 1  &#39; and R 2 , R 2  &#39; are not the same, both of the above reaction sequences give rise to isomeric mixtures of the formula (Ia) products as indicated below. ##STR7## wherein R 1 , R 1  &#39;, R 2 , R 2  &#39;, R 3 , and R 4  are as described above. 
     Diaminoguanidine hydrazones of formula (Ib) may be prepared by the reaction of two molar equivalents of an appropriately substituted aldehyde of formula (Va) dissolved in an organic solvent with an alcoholic or aqueous alcoholic solution of a diaminoguanidine salt of the formula ##STR8## as illustrated in Flow Diagram III(a) below. 
     Uniquely, unsymetrical diaminoguanidines where R 1  ≠R 2  and R 1 , R 1  &#39;≠R 2 , R 2  &#39; may then be obtained cleanly by the novel reaction of a symetrical diaminoguanidine with a minimum of one molar equivalent of hydroxylamine hydrochloride followed by reaction of the thus-formed monosubstituted guanidine with an appropriately substituted aldehyde of formula (Vb) as illustrated in Flow Diagram III(b) below. ##STR9## 
     The Formula (Ib) insecticidal diaminoguanidines may also be converted to insecticidal Formula (Ic) diaminoguanidines by reaction of with 1.0 to 1.25 molar equivalents of an appropriately substituted chloroformate of formula (VI) in an organic solvent such as acetonitrile, ether, toluene, methylene chloride and the like, in the presence of a tertiary amine such as triethylamine or diisopropylethylamine as illustrated in Flow Diagram (IV) below. ##STR10## wherein R 1 , R 1  &#39;, R 2 , R 2  &#39; and R 5  are as described above. 
    
    
     The present invention is further illustrated by the following non-limiting examples. 
     EXAMPLE 1 
     Preparation of p-(2,2,2-trifluoroethoxy)benzaldehyde ##STR11## 
     Potassium hydroxide pellets (85%, 13.2 g, 0.2 mol) are added to 4-hydroxybenzaldehyde (24.4 g, 0.2 mol) and 18-crown-6 (2.6 g, 5% mol) in diglyme (150 mL). The red reaction mixture is stirred for 16 hours at room temperature and then a solution of 2,2,2-trifluoroethyl-p-toluenesulfonate (50.8 g, 0.2 mol) in diglyme (100 mL) is added over 30 minutes, after which the mixture is allowed to stir at room temperature for 45 minutes. The resulting suspension is then heated at reflux for 24 hours. The mixture is cooled to 10° C. and poured into ice water (1300 mL). The organic materials are extracted with ether (4×200 mL), and the extracts washed with 5% sodium hydroxide (2×100 mL), water (2×100 mL) and saturated sodium chloride (1×100 mL), and dried over MgSO 4 . Evaporation of the ether gives an amber oil which is purified by high performance liquid chromatography using silica gel on a Waters 500 unit and 50:50 hexane and methylene chloride as eluant to give 12.3 g of the title product with R f  0.25. Anal. Calcd for C 9  H 7  F 3  O 2  (204.15) C, 52.94; H, 3.43. Found C, 52.04; H, 3.59. 
     EXAMPLE 2 
     Preparation of 1,3-bis{[p-(tetrafluoroethoxy)benzylidene]-amino}guanidine ##STR12## 
     A solution of p-tetrafluoroethoxybenzaldehyde (35.07 g, 0.158 mol) in 2B alcohol (20 mL) is added over 70 minutes to a stirred slurry of diaminoguanidine hydrochloride (9.91 g, 0.079 mol) in 2B alcohol (60 mL) and water (15 mL) at 45° C. The resulting solution is refluxed for one hour, cooled to 5° C. and the hydrochloride salt collected by filtration and washed with cold alcohol and ether to give a white solid (40.5 g, 2 crops, 96%):mp 262°-264° C. 
     The hydrochloride salt (40.53 g, 0.076 mol) is stirred with ethyl acetate (250 mL) and neutralized with aqueous potassium carbonate (3.62 mol, 50 mL). The organic layer is washed with water, dried over Na 2  SO 4 , filtered and evaporated to a yellow solid. Crystallization from benzene-hexane gives the product as a yellow powder (37.4 g, 99%) with mp 125°-130° C. 
     EXAMPLE 3 
     Preparation of 1-amino-3-{[p-(trifluoromethyl)benzylidene]amino}-guanidine, hydrochloride and p-tolualdehyde,α,α,α,-trifluoro-, oxime, (E)- ##STR13## 
     A mixture of 1,3-bis{[p-(trifluoromethyl)benzylidene]amino}guanidine (15.0 g, 0.0374 mol), hydroxylamine hydrochloride (2.76 g, 0.0393 mol) and ethanol (95%, 100 mL) is refluxed for one hour and 30 minutes. After stirring at room temperature for 16 hours, the reaction mixture is cooled in a freezer and the white solid is filtered (7.25 g). The filtrate is evaporated to approximately 30 mL and then cooled. The resulting purple solid (4.4 g) is collected by filtration and reslurried in hot chloroform (75 mL). Filtration gave the title hydrochloride as a white solid with mp 236°-249° C. (dec). 
     The filtrate is evaporated to approximately 10 mL and then cooled. The title oxime is collected by filtration as white powder (1.72 g) mp 98°-102.5° C. 
     Using a similar procedure, 1-amino-3-p{[p-(1,1,2,2-tetrafluoroethoxy)benzylidene]amino}guanidine hydrochloride (white solid, mp 205°-212° C.); 1-amino-3-{p-(trifluoroethoxy)benzylidene]amino}guanidine hydrochloride (white powder; mp 235°-238° C.); and 1-amino-3-(p-chlorobenzylideneamino)guanidine hydrochloride may be prepared. The second products of the reactions, p-(1,1,2,2-tetrafluoroethoxy)benzaldehyde oxime (pinkish white solid, mp 47°-53.5° C.); α,α,α-trifluoro-p-anilaldehyde oxime (off-white solid, mp 46°-49.5° C.) and p-chlorbenzaldehyde oxime may also be isolated from the reactions. 
     EXAMPLE 4 
     Preparation of 1-{[p-(1,1,2,2-tetrafluoroethoxy)benzylidene]amino}-3-{[p-(trifluoromethyl)benzylidene]amino}guanidine ##STR14## 
     p-Tetrafluoroethoxybenzaldehyde (1.7 g) in 4 mL of ethanol is added over three minutes to a stirred and warm mixture of 2.0 g of 1-amino-3-{[p-(trifluoromethyl)benzylidene]amino}guanidine hydrochloride in 9 mL of 8:1 ethanol/water. After heating at reflux for one hour, the mixture is concentrated in vacuo to give 3.6 of a white solid. The solids are dissolved in 150 mL of chloroform and treated with 10 mL of 3.6M potassium carbonate and 50 mL of water containing 5% sodium hydroxide. The product is extracted into ethyl acetate 300 mL and the organic layer washed with salt solution, dried over sodium sulfate and concentrated in vacuo to give 3.3 g of yellow solid. Crystallization from hexanechloroform afforded 2.6 g of the title product as a yellow solid with mp 132°-137° C. 
     Utilizing the procedures of Examples 2 and 4 and substituting the appropriate aldehyde and guanidine yields compounds illustrated below. ##STR15## wherein unless specified R 1  &#39; and R 2  &#39; are H.

     Preparation of 4,4-dimethyl-2-{[p-(1,1,2,2-tetrafluoroethoxy)benzylidene]amino}-allophanimidic acid [p-(1,1,2,2-tetrafluoroethoxy)benzylidene]hydrazide ##STR23## 
     A solution of 1,3-bis{[p-(1,1,2,2-tetrafluoroethoxy)benzylidene]amino}guanidine (29.84 g, 0.06 mol), diisopropylethylamine (15.51 g, 0.12 mol) and dimethylcarbamoyl chloride (129.2 g, 0.12 mol) in acetonitrile (200 mL) is stirred at reflux for 22 hours. The reaction mixture is cooled, and the acetonitrile is evaporated under reduced pressure. The residue is dissolved in ethyl acetate (250 mL), and the organic solution is washed with water, saturated NaCl and dried over Na 2  SO 4 . The solvent is evaporated under reduced pressure, and the residue is crystallized from benzene-hexanes to give the desired product as a yellow solid, mp 141.5°-143.5° C. in 92.9% yield. 
     Utilizing the above procedure and substituting the appropriate dialkylcarbamoyl chloride and diaminoguanidine hydrazone compound, yields the compounds illustrated below.

     EXAMPLE 10 
     The insecticidal activity of the compounds of this invention is demonstrated by the following tests wherein compounds are evaluated against test insect species at rates of from 10 to 1000 ppm. Test formulations and procedures used for evaluation are as follows: 
     Test Formulations 
     A. 100 mg of the test material is weighed, placed in a funnel over a 113 g narrow-mouth bottle, rinsed into the bottle with a 35 mL scoop of acetone, followed by a 35 mL scoop of water and another 35 mL scoop of acetone to yield 1000 ppm in 65% acetone. If the material is not soluble, it is broken up with a glass rod and used as a suspension. 
     B. This stock solution (&#34;A&#34;) is used to make 300 ppm solutions or suspensions by pipetting 30 mL of &#34;A&#34; into a bottle containing 70 mL of 50% acetone to yield 300 ppm. Further dilutions in 50% acetone are made as required. 
     C. Tests requiring 10 ppm acetone solutions: 1 mL of &#34;A&#34; is pipetted into 99 mL of acetone to yield 10 ppm. Additional dilutions are made using 50% acetone as required. 
     Initial Tests 
     Tobacco Budworm-Heliothis virescens (Fabricus). 
     A cotton plant with two true leaves expanded is dipped for three seconds with agitation in 300 ppm solution. A 1.27 to 1.91 cm square of cheesecloth with about 50 to 100 budworm eggs 0-24 hours old is also dipped in the test solution and placed on a leaf of the cotton platn, all being placed in the hood to dry. The leaf with the treated budworm eggs is removed from the plant and placed in a 226 g Dixie cup with a wet 5 cm piece of dental wick and covered with a lid. The other leaf is placed in a similar cup with a wick and a piece of cheesecloth infested with 50-100 newly hatched larvae is added before covering the cup with a lid. After three days at 80° F., 50% relative humidity, observations of egg hatch are made, as well as kill of newly hatched larvae, any inhibition of feeding, or interference of any sort with normal development. 
     Southern Armyworm-Spodoptera eridania (Cramer). 
     A Sieva lima bean plant with just the primary leaves expanded to 1.91 cm is dipped for three seconds with agitation in the &#34;A&#34; solution of 1000 ppm and set in the hood to dry. Following this, one leaf is placed in a 9 cm petri dish which has a moist filter paper in the bottom and 10 third-instar armyworm larvae about 1 cm long. This dish is covered and held at 80° F., and 50% r.h. After two days, mortality counts and estimates of the amount of feeding are made. Compounds showing partial kill and/or inhibition of feeding are held for an extra day for further observations. Those materials which produce greater than 75% mortality, or which show only trace feeding damage are further tested. 
     All compounds showing activity as defined above are retested, using the second leaf on the bean plant, after an interval of seven days from original treatment, as an assay of residual activity. 
     Secondary Tests 
     Tobacco Budworm-Heliothis virescens (Fabricus) 
     Third Instar 
     Three cotton plants with just expanded cotyledons are dipped in 1000 ppm solution and placed in the hood to dry. When dry, each cotyledon is cut in half, and 10 are each placed in a 28 g plastic medicine cup containing a 1.25 cm dental wick saturated with water, and one third-instar budworm larva is added. The cup is capped and held for three days at 80° F., 50% relative humidity, after which mortality counts are made. Compounds killing more than 75% of the larvae are further tested.
