Copper complex of isatin Schiff base encapsulated in zeolite as active heterogeneous catalyst: an efficient protocoludfor the acetylation reaction

摘要

Copper (II) complex of 3-phenylimino-1,3-dihydro-indol-2-one encapsulated in the super cages of zeolite-Yudhas been synthesized by flexible ligand method andudcharacterized by various physicochemical measurements.udThe catalytic activity of cationic exchanged zeolite, copper complex of ligand and complex encapsulated inside the zeolite was investigated for the decomposition of H2O2 and for the acetylation of p-cresol. All catalysts show good to excellent yield. The results showed that conversion of p-cresol varies in the order homogeneous complex NaY-ZeoliteCu-Y-Zeoliteheterogeneous complex
