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 ...
