Immobilization of new Mn(salen) complex over MCM-41 and its activity in asymmetric epoxidation of styrene

Catalysis Letters volume 57, pages 139–143 (1999)Cite this article

Abstract

New tetradentate chelates of bis-Schiff bases were synthesized and then these chiral salen ligands were immobilized over mesoporous MCM-41 by using the ion-exchange method. The efficiency of the chiral catalyst was examined in the asymmetric epoxidation of styrene. Chiral Mn(salen) complexes immobilized onto mesoporous MCM-41 were stable during the reaction without any leaching and exhibited relatively high enantioselectivity for epoxidation as compared with homogeneous complexes.
