We are developing new methods for syntheses of fluorine compounds. We have reported trifluoromethylation of halogen compounds with trifluoromethyl iodide and copper powder'and ene reaction of trifluoromethyl carbonyl compounds? As an extension of this research, we planned to use halothane, 2-bromo-2-chloro-l, l, l-trifluoroethane
