A two-step, on-water procedure for the synthesis of ethenesulfonyl fluoride (ESF) is described. 2-Chloroethanesulfonyl fluoride is made via a neat reaction with an aqueous, nearly saturated potassium bifluoride solution from readily available 2-chloroethanesulfonyl chloride. The subsequent dehydrochlorination of 2-chloroethanesulfonyl fluoride proceeds neatly with magnesium oxide as the base in an aqueous suspension to give ESF. This recipe allows the preparation of ESF in 98% yield on a kilogram scale.

乙磺酰氟（ESF）：千克级制备的水上程序

描述了用于合成乙磺酰氟（ESF）的两步水上程序。2-氯乙烷磺酰氟是通过与几乎饱和的氟化氢钾水溶液进行纯反应，由易于获得的2-氯乙烷磺酰氯制得。随后的2-氯乙烷磺酰氟的脱氯化氢以氧化镁为碱，在水性悬浮液中进行纯净，得到ESF。该配方允许以千克规模以98％的收率制备ESF。
