Use of molecular weight-enlarged catalysts in a process for asymmetric, continous hydrogenation, novel molecular weight-enlarged ligands and catalysts

Abstract

The first embodiment of the present invention provides a process, which includes: in a continuous process in a membrane reactor, asymmetrically hydrogenating at least one C═C, C═N or C═O double bond with a catalyst. Another embodiment of the present invention provides a ligand, which includes at least one di-1,3-aminophosphine homochiral active center; optionally, a linker; and a molecular weight-enlarging polymer; wherein the active center is bound to the molecular weight-enlarging polymer through the linker or is bound directly to the molecular weight-enlarging polymer; and wherein the linker is defined in the claims. Another embodiment of the present invention provides a process for preparing the above-noted ligand, and a catalyst that includes the above-noted ligand.
