INSECTICIDAL SUBSTITUTED BIPHENYL BENZOYLUREAS

Abstract: Insecticidal compounds of formula (I), their preparation and use as insecticides for foliar feeding insects, and insecticidal compositions thereof.

Description: INSECTICIDAL SUBSTITUTED BIPHENYL BENZOYLUREAS The present invention relates to substituted biphenyl benzoylureas, insecticidal compositions thereof, and to a method for controlling insects which damage agricultural or horticultural plants. More specifically the invention relates to selected N-[{(substituted,1'- biphenyl]-4- or 5-yl)amino}carbonyl]-substituted benza- mides which are surprisingly effective in disrupting the normal developmental sequence of foliar feeding insects. ellinga, et al., J. Agr. Food Chem. 2_1(3) (1973), describe the insecticidal activity of substituted biphenyl benzoylureas of formula wherein R is H, Cl, Br, or NO Grosscurt, et al., Pest. Bio. Phys. J_3, 249-254 (1980), describe the Ovicidal and Larvicidal Structure- Activity Relationships of Benzoylureas on the House Fly. A compound of the above formula, in which R is Br,- was included in the ovicidal and larvicidal testing. U.S. patent 4,013,717, issued March 22, 1977, discloses the insecticidal activity of a broad class of benzoyl phenyl urea derivatives, among which are compounds of the general formula OMPI ?NATl in which A and B may be, among other things, hydrogen or halogen but are not both hydrogen, and R p may be a phenyl group substituted with a' wide variety of substituents, among which is a phenyl group optionally substituted with halogen, nitro, cyano or halogenated alkyl. The present invention provides biphenyl benzoylureas of the general type illustrated above, but in which the phenyl ring attached to urea nitrogen (C-ring of formula I) is substitute-d, the terminal phenyl ring (D-ring of formula I) is optionally substituted, and the C-ring is attached at position 4 or 5. • The compounds of this invention exhibit surprisingly high levels of insecticidal activity. The present invention thus provides compounds represented by the formula in which A and B are both halogen or one of A and B is hydrogen and the other of A and B is halogen; R and R f are each independently halogen, alkyl, alkoxy, haloalkyl, haloalkoxy, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, halo- alkylsulfonyl, nitro, or cyano; R" is halogen or alkyl; m is 0 to 3; n is 0 (i.e. R' is hydrogen), 1 to 5 when each R » group is halogen, or 1 to 3 when at least one R' group is not hydrogen or halogen; and the biphenyl group is attached at position 4 or 5. As used in the foregoing description of the substi- tuents and throughout the specification and claims, the term "alkyl", as applied to a substituted group, means a f OMPI saturated hydrocarbyl group of one to six carbon atoms, preferably one to four carbon atoms, most preferably one or two carbon atoms. The terms "halo" or "halogen" mean a halogen atom selected from bromine, chlorine and fluorine. Where multiple halogen or alkyl groups are possible they may be the same or different. The term "haloalkyl" alone or as a component of a larger group means an alkyl group of 1 or 2 carbon atoms, preferably one, substituted with at least 1 halogen atom. These definitions prevail unless a contrary intent is expressly set forth. The compounds of this invention may be prepared by the following schema: (I) (ID A substituted benzamide (I) is heated with oxalyl chloride in methylene chloride to produce a substituted benzoylisocyanate (II). Reaction of (II) with a substi¬ tuted biphenyl amine (III) produces the corresponding N-[{ (substituted!! 1,1 '-biphenyl]-3 or -4-yl)araino}carbon- yl]-substituted benzamide (IV). This general procedure OMPI was described in Wellinga, et al., J. Agr. Food Chem. , 2J., 348 (1973) as Methods A and B and in J. Agr. Food Chem., 21, 993 (1973), both incorporated herein by reference. The intermediate biphenylamines (III) may be pre¬ pared by the following schema: (VI) (III) A substituted nitroaniline (V) and a substituted benzene are treated with t-butylnitrite and copper powder to produce a substituted nitro biphenyl (VI) . Hydrogeπa- tion of (VI) in methanol (a base such as morpholine may be used) produces the desired biphenyl amine (III). In some cases where R is alkoxy and R' is a trifluoromethyl a mixture of isomers was obtained, i.e. a trifluoromethyl group was in the 2', 3', and 4' positions. In order to separate the isomers the following procedure was used: * O-alkyl 3 (III) (VII) mixture of isomers separation of isomers (VIII) isomers separated The appropriately substituted biphenylamine (III), which contained a mixture of isomers, is treated with phthalic anhydride in acetic acid to produce the substi¬ tuted biphenyl phthalimide (VII). Selective crystalliza ¬ tion of (VII) separated some of the isomers and subsequent treatment of the separated isomers with hydrazine hydrate in ethanol provides the substituted biphenylamine (III) as either a single isoraer or a mixture of the 3- and 4-isoraers. • The biphenyl araine intermediates (III) which contain a difluoromethoxy in either the R or R' position may be prepared by the reaction of a phenyl substituted nitro- phenol with chlorodifluoromethane in sodium hydroxide, water and dioxane by the method of T. G. Miller, et al. (J. Org. Chem., 25, 2009 (1960)), subsequent hydrogenation would then produce the desired biphenyl amine intermediate (III). The following examples illustrate use of the fore¬ going methods of preparation. Example 1 2-Chloro-N-[{(2-methoxy[ ' 1,1'-biphenyl]-4-yl)- amino}carbonyljbenzaraide Step A 2-Methoxy-4-nitro[1,1 '-biphenyl] During a one hour period 34.6 g (0.34 mole) of t ^ -butylnitrite was added dropwise to a stirred mixture of 37.6 g (0.22 mole) of 2-methoxy-4-nitroaniline, 874.0 g (11.2 moles) of benzene and 37.6 g of copper powder. After complete addition . the mixture was heated at reflux for approximately 18 hours. The excess benzene was removed by distillation to leave an oil. The oil was purified by column chromatography on silica gel,toluene:- n-heptane (60:40) as eluent, to yield 30.1 g of 2-methoxy- 4-nitro-[ 1,1 '-biphenyl] as a solid, mp 65-66°C.

The nmr and IR spectra were consistent with the proposed structures. OMPI Step C 2,6-Difluoro-N-[{(2-methoxy-(2'-,3 , -,4'-) trifluoromethyl[ 1,1'-biphenyl]-4-yl)amino}- carbonyl]benzamide A mixture of 1.37 g (0.0075 mole) of 2,6-difluoro- benzoyl isocyanate and 2.0 g (0.0075 mole) of 3-methoxy-4- C(2 , -,3'-,4'-)trifluoromethylphenyl]aniline in 100 ml of xylene was stirred at room temperature producing a pre¬ cipitate. The solid was collected by filtration and the filter cake rins-ed with cold n-heptane to yield 3.2 g of 2,6-difluoro-N-C{(2-methoxy(2'-,3'-,4'-)trifluoromethyl- [1,1'-biphenyl]-4-yl)amino}carbonyl]benzamide. Example 3 2,6-Dichloro-N-[{(2',5 * -dichloro-2-methoxy- [1,1*-biphenyl]-4-yl)amino}carbonyl]benzamide Step A 2' ,5'-Dichloro-2-methoxy-4-nitro- [1,1 '.--biphenyl] A mixture of 45.8 g (0.27 mole) of 2-methoxy-4- nitroaniline, 45.8 g of copper powder and 2000 g (13.6 moles) of p-dichlorobenzene was heated at 70-90°C and stirred. After all the p-dichlorobenzene had melted, 421.0 g (0.41 mole) of t_-butylnitrite was added during a one hour period. After complete addition the reaction mixture was stirred at 65°C for approximately 18 hours. The reaction mixture was cooled slightly and diluted with 400 ml of toluene. Excess p-dichlorobenzene was allowed to crystallize and was removed by filtration. The filtrate was passed through silica gel, elution with n-heptane:toluene (1:1); the fractions which contained product were collected and combined. The solvent was- removed to give an oil. The oil was subjected to column chromatography on silica gel, elution with n-hexane:- toluene (9:1), to yield a solid. The solid was purified by recrystallization first from methylcyclohexane then from methanol to yield 16.3 of 2' ,5*-dichloro-2-methoxy- 4-nitro[1 ,1 '-biphenyl] .

The mixture was stirred at room temperature for 2.5 hours then diluted with 60 ml of n-heptane and stirred for an additional half hour. A precipitate formed which was collected by filtration and washed with cold pentane to yield 1.53 g of 2,6-dichloro-N-[{ (2' ,5 » -dichloro-2- methoxy-[ 1,1'-biphenyl]-4-yl)amino}carbonyl]benzamide. Example 4 2,6-Difluoro-N-[{ (2-methoxy[ 1 , 1 ' -biphenyl]-5-yl)- amino}carbonyl]benzamide Step A 2-Methoxy-5-nitro[1 ,1 '-biphenyl] By the method of Example 1 Step A, the reaction of 37.63 g (0.22 mole) of 2-raethoxy-5-nitroaniline, 37.63 g of copper powder, and 34.62 g (0.34 mole) of nitrite, in 874.0 g (11.2 mole) of benzene produced 27.2 g of 2-methoxy-5-nitro[1 ,1 '-biphenyl] as a solid, rap 78-80°C.

Table II sets forth the physical constants for each Compound shown in Table I. The compounds of this invention were tested by incorporating the compounds into the diet of the test insects, second instar southern armyworms and cabbage loopers. The tests were conducted at rates of 200, 20, and 2 ppm, using ten larvae per replicate and two repli¬ cates per rate. Each test was read one day, three to four days, and seven to ten days after infestation to determine the number dead after at least one molt. The test media consisted of a microcrystalline cellulose or clay formation (dust) of the test compound mixed with the insect diet. The formulations of each component of the test media and their method of prepara¬ tion are: Composition of Insect Diet parts by weight Pinto beans 12.90 Wheat germ 5.68 Brewer's dried yeast 3.64 Ascorbic acid 0.37 Methyl paraben 0.23 Sorbic acid 0.11 Sodium benzoate 0.00284 Agar 0.71 Formalin (40?) 0.23 Water 76.13 The agar was dissolved with heating in one-half the water and was brought to a boil. Simultaneously, all other ingredients except the formalin were placed in a blender with remaining water and were reduced to a smooth, homogenous mixture. This mixture was added to the boiling agar. Immediately, the formalin was added with mixing. The compounds of this invention were formulated as either 20$, 5% or 1% dusts* on a microcrystalline cellulose or clay base.

Test media containing 200 ppm of the test compound was prepared by making a 'stock solution' from 250 mg of a 2055 dust formulation stirred well with 5 ml of distilled water in a vial. One milliliter of the 'stock solution' was added to 50 ml of warm, i.e molten, insect diet in a plastic petrie dish which was then mixed thoroughly. After cooling to room temperature, the test media was infested with test larvae and covered. Lower test rates were prepared by dilution of the 'stock solution' according to the following table: Desired Rate ml of ml of (ppm) 'stock solution' water 20 1 9 2 1 ml of 20 ppm solution 9 The results of diet incorporated testing are summarized in Table III.
