Abstract: The invention relates to monocarbonyl complexes of ruthenium and osmium with bi- and tridentate nitrogen and phosphine ligands. The invention relates to methods for preparing these complexes and the use of these complexes, isolated or prepared in situ, as catalysts for reduction reactions of ketones and aldehydes both via transfer hydrogenation or hydrogenation with hydrogen.

Abstract: A new class of ligands derived from benzo[h]quinoline are described and these ligands are used to prepare several novel transition metal complexes. The complexes are preferably of the group VIII transition metals iron, ruthenium or osmium, with the benzo[h]quinolone ligands acting as tridentate ligands. The complexes described are proved to be very active catalysts for the reduction of ketones and aldehydes to alcohols, via hydrogen transfer and hydrogenation reactions. These compounds hence can be usefully employed as catalysts in said reduction reactions.
