New chiral ligands 3 and 5 have been synthesized. Their Ru(II) complexes are effective catalysts for transfer hydrogenation of both aryl alkyl and dialkyl ketones (with ee's up to 79.5%).

The attainment of both high catalytic efficiency and high enantioselectivity remains a formidable challenge in asymmetric catalysis. [1] Bidentate ligands composed of trans-2,5disubstituted phospholane groups have been shown to be useful in asymmetric catalytic hydrogenation reactions. Despite high
