INSECTICIDAL COMPOSITIONS COMPRISING SUBSTITUTED BENZOYL-UREA DERIVATIVES AS ACTIVE INGREDIENT AND PROCESS FOR PRODUCING SUBSTITUTED BENZOYL-UREA DERIVATIVES

Phenoxyphenyl and phenoxypyridyl benzoyl ureas and a process for their preparation are provided. The ureas are useful as the active toxicant in pesticidal compositions and have the general formula: wherein: X is oxygen or sulfur; Y is CR3 or nitrogen; B is oxygen, sulfur, sulfinyl, sulfonyl, oxysulfonyl, sulfonyloxy or carbonyl; R1 and R2 are independently hydrogen, halogen, methoxy, alkyl (C1 - C4) or trifluoromethyl; R3, R4, R5 are independently hydrogen, methoxy, halogen, alkyl (C1-C4) or trifluoromethyl; R6 is hydrogen, halogen or alkyl (C1-C4) or trifluoromethyl; R7, R8 are independently hydrogen, halogen, alkyl (C1-C4), trifluoromethyl, alkylthio (C1-C4), alkylsulfinyl (C1-C4), alkylsulfonyl (C1-C4), or R7 and R8 can optionally be a substituted arylthio, a substituted arylsulfonyl, or a substituted arylsulfinyl, group, wherein said optional substituents are alkyl (C1-C4) or halogen and provided that when B is oxygen, and Y is CR3, at least two of R3-R5 are other than hydrogen.
