An efficient photoredox catalytic radical addition/defluoroalkylation coupling reaction between derivatives of primary amines and trifluoromethyl-substituted alkenes provides a series of gem-difluoroalkenes under visible light irradiation. This reaction offers a broad substrate scope and good functional group tolerance.
