Imidazoline derivatives and salts thereof, their synthesis, pesticidal formulations containing the imidazolines, preparation thereof and their use as pesticides

摘要

Imidazoline compounds of formula (I): IMAGE (I) wherein Ar is selected from a phenyl or a mono-, di- or tri-substituted phenyl radical in which the substituents are selected from alkyl, alkoxy, halogen, hydroxy, cyano, amino, trihalomethyl and nitro and in which any two adjacent carbon atoms of the phenyl ring may be joined by a carbon chain containing 3 or 4 carbon atoms; X1 is S, NR3 or NZ1; R1 and R2 are selected from hydrogen or alkyl; R3 is alkyl or aryl; m is 0 or 1; and Z1 and Z2 are a group SOnR9 or a group IMAGE in which X2 is O, S or NR5; R4 is alkyl, aryl, alkoxy, aryloxy, amino or amido; R5 is alkyl, aryl, alkoxy, aryloxy, alkylthio, arylthio, amino or amido; the alkyl or alkoxy radicals containing from 1 to 4 carbon atoms each; or an acid addition salt of the imidazoline compound. Methods of preparing the compounds are provided, as are pesticidal formulations containing them. The compounds are active against pests, especially arthropods of the Order Acarina.
