FLUOROSUBSTITUTED PHENOXYBENZYL ESTERS OF SUBSTITUTED CYCLOPROPANE CARBOXYLIC ACIDS OR ALPHA-ISOPROPYLPHENYL ACETIC ACIDS, WHICH MAY BE SUBSTITUTED, PROCESSES FOR THEIR PREPARATION AND THEIR APPLICATION AS INSECTICIDES AND ACARICIDES; FLUOROSUBSTITUTED PHENOXYBENZYL ALCOHOLS AND FLUOROSUBSTITUTED PHENOXYBENZYL HALIDES

摘要

Fluorine substituted phenoxybenzylcarbonyl derivatives of the formula in which R1 represents hydrogen, cyano or ethynyl and R2 represents the radical wherein R3 and R4, which are identical, each represent chlorine, bromine or methyl, or R2 represents the radical wherein R5 represents a phenyl ring which optionally carries one or more substituents each selected independently from halogen, alkyl, alkylthio and alkoxy each with 1-4 carbon atoms, nitro and methylenedioxy, which possess arthropodicidal properties. The benzyl alcohol components of these esters are also new.
