Electrophilic alkenylation of fluoroolefins by perfluoro(2-alkoxypropenes)
摘要:
Perfluoro(2-alkoxypropenes) react with tetrafluoroethylene under mild conditions in the presence of SbF5 to give the corresponding perfluoro(2-alkoxy-2-pentenes). 1-Trifluoromethoxyperfluoropropene is converted by the action of SbF5 in SO2ClF solution to the acid fluoride derivative of perfluoroacrylic acid.
