Abstract

2,2-Dimethyl-3-(2'-perfluoroalkyl-2'-perhaloalkyl-vinyl)-cyclopropane of the formula ##STR1## in which R is --COOR.sup.2, --COOH, --CO--Halogen, --CN or --CO--CH.sub.3, PA1 R.sup.1 is fluorine or CF.sub.3, PA1 R.sup.3 is fluorine, chlorine, bromine or R.sup.1 CF.sub.2 --, and PA1 R.sup.2 is the radical of an alcohol which possess arthropodicidal properties. These compounds can be produced by adding a compound of the formula ##STR2## to an olefin of the formula ##STR3## to produce a compound of the formula ##STR4## and dehydrohalogenating said compound. This compound may be hydrolyzed, saponified or esterified, depending upon the particular derivative desired.
