Ruthenium(II) complexes bearing a pyridyl-supported pyrazol-3-yl-N-heterocyclic carbene (NNC) ligand were synthesized from the reactions of RuCl3 center dot 3H(2)O with pyridyl-supported pyrazol-3-yl-imidazolium salts in the presence of carbon monoxide. These Ru(II) complexes have exhibited good to excellent catalytic activity in the transfer hydrogenation of ketones in refluxing 2-propanol. Formation of a coordinatively unsaturated Ru(II) center in the precatalyst is attributed to the high catalytic activity of the Ru(II) complexes.
