  • 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.
