The present invention is directed to methods for preparing a fluorosulfonate ester or a salt thereof, through a reaction of a dissolved sulfonyl fluoride (R
F
SO
2
F) with alkoxide anion (RO
−
) optionally in the presence of an aprotic base (B), where R
F
is fluorine or a C
1
-C
8
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.
本发明涉及制备
氟磺酸酯或其盐的方法,通过将溶解的磺酰
氟(RFSO2F)与醇酸根阴离子(RO−)反应,可选地在无
水碱(B)的存在下进行,其中RF为
氟或C1-C8
全氟烷基,R为一级烷基或烷氧基烷基。醇酸根阴离子(RO−)可以从前体物如醇或
硅酯中生成。
