Mesoporous cross-linked polymer copolymerized with chiral BINAP ligand coordinated to a ruthenium species as an efficient heterogeneous catalyst for asymmetric hydrogenation.

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.
