3-CHLORO- AND 3-BROMOHEPTAFLUORO-1-BUTENES. SYNTHESIS AND CATALYTIC REARRANGEMENTS

3-Chloroheptafluoro-1-butenes and 3-bromoheptafluoro-1-butenes were obtained by dehydrohalogenation of 1-hydro-2,3-dichloro- and 1-hydro-2,3-dibromo-heptafluorobutenes.It was shown that the rearrangement of 3-bromoheptafluoro-1-butene, catalyzed by antimony pentafluoride, is accompanied by migration of the bromine atom and leads to 1-bromoheptafluoro-2-butene.Under analogous conditions 3-chloroheptafluoro-1-butene isomerizes to 2-chloroheptafluoro-2-butene.
