Abstract:
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.
