We report here a successful preparation of a heterogeneous chiral catalyst from copolymerization of mesoporous cross-linked polymer with chiral BINAP ligands, followed by coordination of the BINAP with a ruthenium species, which exhibits high activity, excellent enantioselectivity, and extraordinary recyclability in asymmetric hydrogenation.
我们在这里报告了一种成功的非均相手性催化剂的制备方法,该方法是由中孔交联聚合物与手性BINAP配体共聚,然后将BINAP与钌物种配位,该化合物在不对称氢化中表现出高活性,优异的对映选择性和出色的可回收性。
