Defluorinative alkylation of 1-trifluoromethyl alkenes with alkyl radicals derived from visible light-induced deoxygenation of xanthate salts: synthesis of gem-difluoroalkenes

A visible light-induced deoxygenative difluoroallylation of alcohols via xanthate salts with trifluoromethyl alkenes under catalyst- and metal-free conditions is presented.
