WebA new fluorine reagent, trifluoromethanesulfonyl chloride, is discussed in this paper. The reagent not only yields sulfonation products with active hydrogen containing compounds but also forms stable compounds with tertiary nitrogen bases, presumably by a Lewis acid-Lewis base reaction. Webyields. Moreover, the reaction was compatible with cyclic and acyclic branched enol acetates. Quite interestingly, when the reaction was performed using an aryl or alkylsulfonyl chloride, instead of trifluoromethanesulfonyl chloride, no extrusion of the SO2 moiety was observed, and the sulfonated products were recovered.
