Abstract

Some metal hydrogen sulfates were used as acid catalysts in the N-acylation of different sulfonamides using carboxylic acid chlorides and anhydrides as acylating agents under both heterogeneous and solvent-free conditions. Al(HSO 4 ) 3 and Zr(HSO 4 ) 4 were found to have the highest activity and catalyze the reactions efficiently to furnish the primary N -acyl sulfonamides (RCONHSO 2 R′), secondary N -acylsulfonamides (RCONR″SO 2 R′) and bis- N -acylsulfonamnides [RCO(SO 2 R′)N-R″-N(SO 2 R′)COR] in good to high yield. The mild reaction conditions, inexpensive and low toxicity of catalysts and easy work-up procedure make this method attractive.
