Crosslinked polymers containing chiral N-sulfonylated diamine (TsDPEN) structure were synthesized by radical polymerization of chiral N 1 -(4-vinylbenzenesulfonyl)-1,2-diphenylethylene-1,2-diamine, divinylbenzene and achiral vinyl monomer. The polymer-immobilized chiral complex was prepared from the polymeric TsDPEN with ruthenium dichloride p-cymene. Asymmetric transfer hydrogenation of cyclic...
