Abstract :
A new chiral dipyridylphosphine ligand Xyl-P-Phos has been synthesized and the structure of (S)-Xyl-P-Phos oxide has been characterized by single crystal X-ray diffraction. The ruthenium complex of this ligand, Ru(R-Xyl-P-Phos)(C6H6)Cl2, has been found to be a highly active, enantioselective and air-stable catalyst for the asymmetric hydrogenation of β-ketoesters and shows good potential for industrial applications.
