WebScribd is the world's largest social reading and publishing site. In coupling reactions between aromatic compounds and metal-trifluoromethyl complexes the metal is usually copper, Pd and Ni are less prominent. The reactions are stoichiometric or catalytic. In the McLoughlin-Thrower reaction (1962) iodobenzene reacts with trifluoroiodomethane (CF3I) and copper powder in dimethylformamide at 150 °C to trifluoromethylbenzene. The intermediate in this reaction type is a perfluoromethyl-metal complex.
