摘要：

The synthesis of three different polymer-bound chiral Mn-salen complexes (Poly-1, -2a, -2b) is reported, along with their application as recyclable catalysts in heterogeneous asymmetric epoxidation with mCPBA/NMO of several unfunctionalized olefins. The introduction of a spacing group between the polymeric chain and the metal centre (Poly-2a and -2b) considerably increased the enantioselectivity of the process.
