Abstract
Perhaloalkylvinylcyclopropanecarboxylates having the general formula ##STR1## are disclosed wherein one of Y and Z is a perhaloalkyl group and the other is hydrogen, halogen, or lower alkyl. Compounds in which R is hydroxy, halogen or lower alkoxy are intermediates for preparation of insecticidal esters in which R is an optionally substituted benzylfurylmethoxy group. The insecticidal efficacy and preparation of the compounds and intermediates therefor are described and exemplified.
