Electrophilic condensation of 1-hydroperfluoropropylene and 1-hydroperfluoro-1-butene with fluoroethylenes

Conclusions 1-Hydroperfluoropropylene reacts with tetrafluoroethylene in the presence of SbF₅ to form the corresponding 11 and 12 adduct olefins. The condensation is accomplished at both the CFH and CF₂ groups of the starting propylene. Under analogous conditions, 1-hydroperfluoro-1-butene condenses with fluoroethylenes exclusively at the CFH group.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1591–1594, July, 1982.
