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, Rs 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, alkytthio (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.
