A ruthenium-catalyzed reductiveaminationwithout an externalhydrogensource has been developed using carbon monoxide as the reductant and ruthenium(III) chloride (0.008–2 mol %) as the catalyst. The method was applied to the synthesis of antianxiety agent ladasten.

First osmium-catalyzed reductive amination under the water gas–shift reaction conditions was developed. Proposed catalytic system demonstrates high performance even at the catalyst loading as low as 0.0625 mol%.
A Diaminocyclopentadienone iron tricarbonyl complex has been applied in chemoselective hydrogen transfer reductions. This bifunctional iron complex demonstrated a broad applicability in mild conditions in various reactions, such as reduction of aldehydes over ketones, reductive alkylation of various functionalized amines with functionalized aldehydes and reduction of α,β-unsaturated ketones into the
