The invention relates to a series of novel chiral phosphorus ligands of formulae (Ia) and (Ib): wherein R, 1 - rR> 4 and X are as defined herein. The invention also relates to chiral metal complexes prepared with these chiral phosphorus ligands. The chiral metal complexes are useful as catalysts for carrying out asymmetric hydro genation.
本发明涉及一系列新颖的具有公式(Ia)和(Ib)的手性磷配体:其中R,1 - rR> 4和X如本文所定义。本发明还涉及用这些手性磷配体制备的手性金属配合物。手性金属配合物可用作实施不对称氢化的催化剂。
