• N-substituted benzimidazoles (L) were prepared.
• Half sandwich Ru-(II) complexes were synthesized and characterized.
• All novel complexes first used as a catalyst for the N-alkylation reaction.
Half sandwich ruthenium(II) complexes were synthesized from [RuCl2(η6-p-cymene)]2 and N-substituted benzimidazole. All new compounds were characterized by elemental analysis, 1H NMR, 13C NMR, and IR spectroscopy. Aminoarenes were readily converted into secondary amines by the reaction at 150 °C with benzyl alcohol and in the presence of a catalytic amount of novel ruthenium complexes. All of [RuCl2(η6-p-cymene)(N-substituted benzimidazole)] complexes were the most effective catalyst for N-alklyation reaction using borrowing hydrogen methodology.
