  • Publication number: 20050101813
    Abstract: A molecular weight-enlarged, homogeneously soluble ligand, useful in catalysts, particularly for the synthesis of enantiomerically enriched organic compounds, includes: a weight average molecular weight of at least 1000 g/mol; a molecular weight-enlarging polymer; optionally, a polymer linker; and at least one homochiral active center; wherein the active center is bound to the molecular weight-enlarging polymer through the polymer linker or is bound directly to the molecular weight-enlarging polymer.

  • Patent number: 6759559
    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.
