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.

Reductiveeliminations to form alkyl–nitrogen bonds are rare, and examples of this reaction from isolated complexes containing simple, unstabilized primary alkyl groups have not been observed. We report the synthesis of stable neopentylpalladium(II) anilido and methyleneamido complexes that undergo reductiveelimination to form the C(sp3)–N bonds in N-neopentyl anilines and N-neopentyl imines, respectively

Experimental and DFT calculation data revealed that the benzene ligand in 2a is more labile than that in the related cyclopentadienyl complexes [(C5R5)Rh(C6H6)]2+. Complex 2c effectively catalyzes the reductiveamination reaction between aldehydes and primary (or secondary) amines in the presence of carbon monoxide, giving the corresponding secondary and tertiary amines in very high yields (80–99%). This protocol

compounds with amines by photoredoxcatalysis proceeds in good to excellent yields and with broad substrate scope and good functional group tolerance. The three key features of this work are 1) the rapid interception of electron‐rich α‐aminoalkyl radical intermediates by polarity‐matched HAT in a photoredox reaction, 2) the method of reductive amination by photoredoxcatalysis itself, and 3) the application

A method of reductiveaminationwithout an externalhydrogensource is reported. Carbon monoxide is used as the reductant. The reaction proceeds efficiently for a variety of carbonyl compounds and amines at low catalyst loadings and is mechanistically interesting as it does not seem to involve molecular hydrogen.
