CuCl-Catalyzed Isomerization of gem-Chlorofluoro-Cyclopropanes into Chlorofluoroalkenes

CuCl-catalyzed isomerization of gem-chlorofluorocyclopropanes into chlorofluoroalkenes occurs as a result of the ring opening accompanied by the migration of chlorine atom. In the case of vinyl- or cyclopropyl-containing substrates, chlorofluoroalkadienes are formed.
