Zinc Oxide Catalyzed Efficient Synthesis of Sulfonamides under Mild Conditions

G. A. Meshram and Vishvanath D. Patil

A simple and efficient procedure for the synthesis of sulfonamides has been described. This method has been applied to a variety of substrates including nucleophilic and sterically hindered amines with excellent yields of sulfonamides. The remarkable selectivity under mild and neutral conditions, of this commercially available inexpensive catalyst is an attractive feature of this method
