The invention relates to a process for the preparation of a benzoylurea compound of the general formula I, in which the meaning of the substituents can be found in the patent claim. Preferably, A, B and X are independently fluorine, chlorine or methyl; Y is chlorine, nitro, cyano or trifluoromethyl, Z is chlorine, cyano or nitro; Q is N-morpholinyl, N-piperidonyl, N-pyrrolidonyl, N-morpholinoyl or a group CR 2 R 3 R 4 with R 2 is alkyl, R 3 is alkylcarbonyl or alkoxycarbonyl and R 4 is alkyl, alkylcarbonyl or alkoxycarbonyl. For example, diethyl is 4- & 4- & 2-chloro-4- (trifluoromethyl) phenoxy! -2-fluorophenyl! -7- (2,6-difluorophenyl) -5,7-dioxo-3-thia-4,6-diazaheptane 2,2-dicarboxylate. The compounds prepared according to the invention are useful as pesticides, e.g. As insecticides and acaricides suitable. Formula I |
