originally occupied by the bromine. Formation of pentafluoroethyl compounds is explained by decomposition of trifluoromethylcopper to cuprous fluoride and difluorocarbene, which can then react with a further molecule of trifluoromethylcopper to form pentafluoroethylcopper. This then reacts with aryl halide to give pentafluoroethyl compounds. Perfluoroalkylcopper is thermally cleaved to perfluoroalkyl radical
