The catalytic activity and selectivity of catalysts 1a, 1b were explored for the asymmetric epoxidation of unfunctionalized olefins using m-CPBA as an oxidant system. Interestingly, the immobilized chiral salen-Mn(III) catalyst shows higher yields and chiral induction in the absence of NMO than that obtained in the presence of NMO. This stands in contrast to the literatures reported. Especially for the epoxidation of α-methylstyrene (yield%: from 14.3% to 60.9%|ee%: from 29.4% to 73.7%), and the catalyst 1b shows more 21.7% ee values was observed than corresponding homogeneous catalyst, similar pattern was reported in the epoxidation of styrene and indene, which may overcome the last obstacle for the potential industry application of chiral Jacobsen s catalyst. And we also preliminary studied the attack-oriented to intermediates.

Key words: axially coordinated immobilization, asymmetric epoxidation of unfunctionalized olefins, chiral Jacobsen s catalyst, phenoxyl modified, zirconium poly(styrene-phenylvinylphosphonate)-phosphate
