Abstract: A new and convenient procedure was developed for the preparation of sulfonamides and sulfonic esters using N-fluorobenzenesulfonimide(NFSI) as a novel phenylsulfonyl group transfer reagent. In this protocol, a broad range of functional groups were tolerated to give the corresponding sulfonamides or sulfonic esters in moderate to excellent yields. The synthetic strategy for sulfonamides formation proceeded efficiently even under base-, metal-and additive-free conditions with the advantages of operational simplicity, mild reaction conditions as well as short reaction time.

Key words: N-Fluorobenzenesulfonimide, Sulfonylation, Sulfonamide, Sulfonic ester
