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.

N-alkyl-N-1-naphthylformamides has been measured in a series of solvents using NMR spectroscopy. A linear relationship was found between the free energy of the conformationalequilibrium, ΔG0, and the relative dielectric permittivity of the solvent. The comparison of NMR data with quantum-chemically calculated SCRF heats of equilibria reveals that the solvent effect is a combination of both the electrostatic and
