FLUORINE-SUBSTITUTED OXYALKENYL-CYCLOPROPANECARBOXYLIC ACID ESTERS, A PROCESS FOR THEIR PREPARATION AND THEIR USE AS INSECTICIDES AND ACARICIDES

摘要

2,2-Dimethyl-3-(2-fluoroalkyl-2-oxy-vinyl)-cyclopropane-carboxylic acid esters of the formula in which R1 is fluoroalkyl, R2 is an optionally substituted alkyl, cycloalkyl, aralkyl or aryl radical, and R3 is a radical customary in the alcohol component of pyrethroids which possess arthropodicidal properties. New intermediates therefor are also shown.
