The utilization of copper/zeolite as catalyst in the microwave-assisted synthesis of some novel sulfonamide derivatives

Zeolite Y clay modified copper nitrate catalyst was prepared. The obtained catalyst was analyzed by SEM, EDS, and powder XRD techniques. The zeolite Y clay modified copper nitrate catalyst was used for the synthesis of various substituted mesalazine by sulfonylation. The synthesized sulfonamides have been characterized by GC-MS, IR, ¹H, ¹³C and HSQC NMR techniques. The yield percentages of sulfonamides are more than 85%.
