Chloro, difluoromethylation and chloro, carbomethoxydifluoromethylation: reaction of radicals derived from RfSO2Cl with unactivated alkenes under metal-free conditions.

Abstract

Difluoromethyl and carbomethoxydifluoromethyl radicals were generated from their respective sulfonyl chlorides under mild, metal-free conditions leading to efficient atom transfer radical additions (ATRA) to unactivated alkenes to form chloro, difluoromethylated and chloro, carbomethoxydifluoromethylated products.
