PROCESS FOR THE PREPARATION OF 1-ARYL-CYCLOPROPANE-1-CARBOXYLIC ESTERS HAVING PESTICIDAL SPECIALLY INSECTICIDAL AND ACARICIDAL EFFECTS

摘要

1-Aryl-cyclopropane-1-carboxylic acid esters of the formula IMAGE in which R1 represents a hydrogen atom, a cyano radical or an alkyl, alkenyl or alkinyl radical within each case up to 7 carbon atoms, and R2 represents a phenyl radical which is substituted by halogen and/or optionally halogen-substituted phenoxy, with the proviso that the radical R2 in total contains at least one fluorine substituent, R3 and R4, which can be identical or different, represents a fluorine, chlorine or bromine atom or a methyl radical, R5 represents a hydrogen or halogen atom or a methyl or methoxy radical, and R6 represents a hydrogen or halogen atom, a cyano nitro or amino radical or an optionally halogen-substituted radical selected from C1 to C4 alkyl, C1 to C4 alkoxy and C1 to C4 alkylthio, or wherein the two radicals R5 and R6 together represent an optionally halogen-substituted C1 or C2 alkylenedioxy radical, which possess pesticidal properties.
