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.

coordinated at the central ring was applied in catalysis for the first time. As a result, a simple and efficient protocol for reductive amination that involves CO as a reducing agent has been developed. The rhodium complex [(cyclooctadiene)Rh(C10H4Me2(OMe)4)]+ (1 mol%) catalyses such reactions undermildconditions (40–130 °C) and produces a variety of amines in good yields (74–95%) without affecting the functional

Palladium-catalyzed amination of isomeric bromochloro- and dibromobenzenes with 1- and 2-aminoadamantanes was studied. The best yields of the corresponding monoamination products were obtained in the reactions of 2-aminoadamantane with bromochlorobenzenes. The arylation of 1-aminoadamantane was successful in the presence of donor phosphine ligand. The amination of o- and m-dibromobenzenes was strongly complicated by formation of diamination products. Conditions ensuring predominant formation of the latter were found. The arylation of 2-aminoadamantane was accompanied by oxidation of the initial amine and reduction of aryl halide.
