A new polymer-supported camphor-derived sulfide catalyst was prepared. Compared with the homologous catalyst, the immobilized catalyst exhibited higher enantioselectivity in asymmetric epoxidation of benzaldehydes and benzyl bromide. The catalyst can be recycled at least 5 times with only minimal loss of catalytic performance.
