Perfluoroalkanosulfonyl fluorides (RfSO2F) are stable,non-toxic,moisture-tolerant and cost effective reagents. In industry, they have been widely empolyed as precursors for the synthesis of highly valued surfactants,pefluoroalkanesulfonic acid salt RfSO3M. Due to the excellent leaving ability of perfluorosulfonate anion(RfSO3-), RfSO2F has been explored and used as an excellent hydroxyl group-activating reagent for fluorination of alcohols to synthesize fluorides, for cyclodehydration of chiral vicinal diols, N-acylamino alcohols, ß-hydroxy sulfonamides and ß-hydroxy thioamides for the synthesis of epoxides and other heterocyclic compounds, for the preparation of acid-sensitive from the substrate of a,ß-unstaturated ketoximes, for dehydration of aldoximes to nitriles, and for the synthesis of diphenylphosphinate esters via the reaction of diphenylphosphine oxide with alcohols.
