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.
