Reactions of perfluorovinylsulfonyl fluoride, CF2=CFSO2F (1), with SO3 forms the novel β-sultone cyclo (2) in good yield.Compound 2 undergoes ring-opening upon heating or reaction with fluoride ion to give F(O)C-CF(SO2F)2 (3).Hydrolysis of 3 and 2 yields the new compounds CHF(SO2F)2 (4) and HO3S-CHF-SO2F (5), respectively.
