An effective approach toward conversion of phenols to their benzene sulfonate esters by using N-fluorobenzenesufonimide (NFSI) and catalyticpotassium fluoride is demonstrated. Mild reaction conditions, shorter reaction time, excellent yield and easy-to-handle reagents are the key features of the methodology. Mild reaction conditions have conferred wide substrate tolerability and sensitive substrates

benzenesulfonyl fluoride directs chemoselective cleavage of aryl silyl ethers over aliphatic silyl ethers. Electron withdrawing substituent’s on aryl ring provided better yield than donating groups. Protecting groups and sensitive functionalities are well tolerated in this methodology. Thus, commercially available inexpensive reagents, mild reaction conditions and step economy are the advantages of this method
