摘　　要：Jacobsen’s catalyst was immobilized onto SBA-15 by multi-step grafting, and this new heterogenized catalyst exhibited comparable catalytic performance with the corresponding homogeneous counterpart for the epoxidation of alkenes.When NH4OAc were used as cocatalyst both yields and ee’s were higher than that of without co catalyst.Jacobsen's catalyst was immobilized onto SBA-15 by multi-step grafting, and this new heterogenized catalyst exhibited comparable catalytic performance with the corresponding homogeneous counterpart for the epoxidation of alkenes.When NH_4OAc were used as cocatalyst both yields and ee's were higher than that of without co catalyst.
