The present invention discloses and exemplifies alcohol, ether and ester derivatives of difluoroalkanes and difluoroalkenylalkanes having the general formula R--(CH.sub.2).sub.m --CR.sup.2 R.sup.3 --OR.sup.1, in which R is a 1,1-difluoroalkyl or a 1,1-difluoroalkenyl group, composition thereof, and use thereof to control agricultural crop pests.
A new type of bench-stable yet highly reactive fluoroalkylating reagents, 3,3-difluoroallyl sulfonium salts (DFASs), has been developed. The reaction of DFASs with aromatic and aliphatic zincreagents via copper catalysis provides general and practical access to a wide range of versatile gem-difluoroallylated compounds with high regioselectivity.
