It was shown that the epoxidation of polyfluoro-2-butenes containing chlorine or bromine atoms at the α or β position with sodium hypochlorite has lower selectivity than the reaction with internal perfluoroalkenes.The reactions of chlorine and bromine-containing 2,3-epoxypolyfluorobutanes with a series of nucleophilic and electrophilic reagents were conducted.It was noticed that the opening of their epoxide ring by antimony pentafluoride is accompanied by migration of the chlorine or bromine atom.With nucleophilic reagents the ring of 1-chloro- and 1-bromo-2,3-epoxyheptafluorobutanes opens in both possible directions.
