Abstract

A convenient photoredox-catalyzed defluorinative trifluoromethylation of α-trifluoromethyl alkenes and gem-difluoroalkenes is developed. The reactions proceeded efficiently via trifluoromethyl radical addition followed by β-fluorine elimination process, providing a new entry to multifluorinated alkenes in moderate to good yields with excellent stereoselectivity. (Figure presented.).
