摘要

Manganese-exchanged Al-MCM-41 modified by the chiral salen ligand [(R, R)-(−)-N, N [hair space]′-bis (3, 5-di-tert-butylsalicylidene) cyclohexane-1, 2-diamine] has been investigated as a heterogeneous catalyst for the enantioselective epoxidation of (Z [hair space])-stilbene using iodosylbenzene as oxygen donor, with particular interest in the effect of reaction conditions on the cis∶ trans ratio of the epoxide product. Immobilisation of the chiral Mn– ...
