In this article, direct N-alkylation reactions of amines with alcohols derivatives have been investigated. For this purpose, a new series ruthenium (II) complexes bearing N-coordinated benzimidazole complexes with have been synthesized and fully characterized by elemental analysis, FT-IR, 1H NMR and, 13C NMR spectroscopies. Additionally, the structures of the complexes 2b and 2c have been confirmed by X-ray crystallography. Although the N-alkylating reaction is usually performed in toluene, the catalytic study of complexes 2a-d has carried out no additional solvent and alcohol acted both as solvent and reactant of alkylating by using a little excess of alcohols. Surprisingly, conversion and selectivity of amine product for alkylation reaction have been seen high in medium solvent-free relative to in toluene.

Abstract: A mild and eco-friendly method has been developed for the synthesis of a series of 1,3-diaminopropan-2-ols 8a–n. The epoxide of epichlorohydrin undergoes ring-opening with amines using MgSO4 or mixed metal oxides catalysts under mild

A ruthenium-catalyzed reductive amination without an external hydrogen source 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.
