The present invention is directed to methods for preparing a fluorosulfonate ester or a salt thereof, through a reaction of a dissolved sulfonyl fluoride (RFSO2F) with alkoxide anion (RO- ) optionally in the presence of an aprotic base (B), where RF is fluorine or a C1-C8 perfluoroalkyl group, and R is a primary alkyl or alkoxyalkyl. Alkoxide anion (RO-) can be generated from a precursor such as an alcohol or silyl ester.
本发明涉及通过将溶解的磺酰
氟化物(RFSO2F)与烷氧基阴离子(RO-)在有无无
水碱(B)的情况下反应,制备
氟磺酸酯或其盐的方法,其中RF为
氟或C1-C8
全氟烷基基团,R为一次烷基或烷氧基烷基。烷氧基阴离子(RO-)可以由醇或
硅酯等前体生成。
