摘要：
Chiral Mn(salen) complexes axially immobilized onto insoluble polymers by phenoxy group or phenyl sulfonic group afford comparable or even higher enantioselectivities than homogeneous Mn(salen) catalysts for the asymmetric epoxidation of various unfunctionalized olefins. These heterogeneous Mn(salen) catalysts are relatively stable and can be recycled in the asymmetric epoxidation. (C) 2005 Published by Elsevier Ltd.
