Chloro, Difluoromethylation and Chloro, Carbomethoxydifluoromethylation: Reaction of Radicals Derived from RfSO2Cl with Unactivated Alkenes under Metal-Free Conditions

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.
