Synthesis of salen Mn(III) immobilized onto the ZnPS-PVPA modified by 1,2,3-triazole and their application for asymmetric epoxidation of olefins
چکیده انگلیسی

A series of chiral salen Mn(III) complexes immobilized onto ZnPS-PVPA modified by 1,2,3-triazole through click chemistry were synthesized. High yields and comparable enantioselectivities were achieved in asymmetric epoxidation of unfunctional olefins with NaClO/PPNO and m-CPBA/NMO as well as NaIO4/imidazole as the oxidative systems. The catalytic results indicated that the catalysts were selective for oxidative systems and the additives played different roles in different oxidative systems. Moreover, the superior reusability and catalytic abilities in large-scale reactions at the same level demonstrated the potentiality for application in industry.
