REACTIONS OF CHLORINE MONOFLUORIDE. V. REGIOSPECIFICITY AND STEREOCHEMISTRY IN THE ADDITION OF CHLORINE MONOFLUORIDE TO E- AND Z-1-BROMO-2-CHLOROETHYLENES AND 1,2-DIBROMOETHYLENES

The chlorofluorination of Z- and E-1-bromo-2-chloroethylenes and 1,2-dibromoethylenes with hexachloromelamine in anhydrous hydrogen fluoride and with chlorine monofluoride in Freon 113 was investigated.The addition of ClF at the multiple bond of alkenes is nonregiospecific and nonstereospecific.The direction and stereochemistry of addition depend on the reagent, the substrates, and the medium.The mechanism of chlorofluorination was examined, and it was shown that in both media the reaction takes place with the participation of chloronium and bromonium carbocationic intermediates.
