摘要：

A dimeric Cr(salen) catalyst was successfully immobilised in a silica-supported ionic liquid. The heterogeneous catalyst offers very high selectivity and good reactivity for asymmetric ring-opening reactions of epoxides. It can be used in a continuous-flow reactor as an alternative for the homogeneous reaction. (c) 2006 Elsevier Inc. All rights reserved.
