Porous Rh/BINAP polymers as efficient heterogeneous catalysts for asymmetric hydroformylation of styrene: Enhanced enantioselectivity realized by flexible chiral nanopockets

A series of polymer-supported Rh catalysts were obtained through the copolymerization of (S)-5,5′-divinyl-BINAP and other co-monomers. The heterogeneous catalyst exhibited higher enantioselectivity than the corresponding homogeneous complex owing to the presence of flexible chiral nanopockets.
