N-Sulfonylation of amines, imides, amides and anilides using p-TsCl in presence of atomized sodium in EtOH-THF under sonic condition

摘要

A simple, facile and an efficient procedure for the N-sulfonylation of amines, imides, amides and anilides using p-TsCl in the presence of atomized sodium in a mixture of EtOH-THF under sonic condition is developed. The method is rapid, mild and inexpensive; yields are high and the reactions go to completion within 2-8 min. © 2015 Elsevier B.V.
