Treatment of L3a-d and L4a-d with [Ru(p-cymene)Cl2]2 led to the formation of [Ru(p-cymene)(IPR)Cl]Cl (RuL3a-d) and [Ru(p-cymene)(IPR')Cl]Cl (RuL4a-c). New ruthenium(II) complexes RuL3a-d and RuL4a-c were characterized by elemental analysis, FTIR, UV-visible and NMR spectroscopy. In order to understand effects of these changes on the N-substituent of imidazol on IP and how they translate to catalytic activity, these new RuL2, RuL3a-d and RuL4a-c were applied in the transfer hydrogenation of ketones by 2-propanol in presence of potassium hydroxide. The activities of the catalysts were monitored by NMR and GC analysis. © 2013 Elsevier Ltd.
