Abstract
Process for catalytically hydrogenating carbon-heteroatom double bonds, in particular for asymmetrically catalytically hydrogenating simple ketones, which includes the step of reacting the substrate with hydrogen in the presence of a hydrogenation catalyst and of a base, characterized in that the hydrogenation catalyst is a 5-coordinate ruthenium complex which in each case has a monophosphine ligand and a bidentate P-N ligand.
