Abstract

Half sandwich ruthenium(II) complexes were synthesized from [RuCl2(eta(6)-p-cymene)](2) and N-substituted benzimidazole. All new compounds were characterized by elemental analysis, H-1 NMR, C-13 NMR, and IR spectroscopy. Aminoarenes were readily converted into secondary amines by the reaction at 150 degrees C with benzyl alcohol and in the presence of a catalytic amount of novel ruthenium complexes. All of [RuCl2(eta(6)-p-cymene)(N-substituted benzimidazole)] complexes were the most effective catalyst for N-alklyation reaction using borrowing hydrogen methodology. (C) 2014 Elsevier B. V.
