摘　　要：Heterogeneous asymmetric catalysis is an important strategy for the industrial production of chiral compounds.Herein,we reported a polymer-bound Xu-Phos-derived palladium catalyst that shows good performance in heterogeneous asymmetric reductive Heck reaction of allyl aryl ethers.This heterogeneous catalyst was easily prepared by efficient immobilization of the sulfonamide phosphine ligand(Xu-Phos)in the cross-linked polystyrene via copolymerization,and exhibits similar catalytic activity and enantioselectivity to that of the homogeneous catalyst.Moreover,the heterogeneous catalyst system is proved to be easily recovered and reused several times without losing catalytic activity obviously.
