Application of dinuclear ru thenium(II) arene complexes in transfer hydrogenation of ketones

13347

The ability of transition metal catalysts to add or remove hydrogen from organic substrates by transfer hydrogenation process is a valuable synthetic tool. For this aim, a series of metal complexes with a P-O ligand, N3,N3 -di-2-(diphenylphosphino)benzylidene-[2,2 ]bipyridinyl-3,3 -diamine derived from N3,N3 - di-2-hydroxybenzylidene-[2,2 ]bipyridinyl-3,3 -diamine were synthesized. Reaction of N3,N3 -di-2- (diphenylphosphino)benzylidene-[2,2 ]bipyridinyl-3,3 -diamine with [Ru(h6-benzene)(μ-Cl)Cl]2 or [Ru(η^6- p-cymene)(μ-Cl)Cl]2 gave bridged dinuclear complexes [C24H16N4{OPPh2-Ru(η^6-benzene)Cl2}2] 1 and [C24H16N4{OPPh2-Ru(η^6-p-cymene)Cl2}2] 2, respectively. Ru(II)-bisphosphinite complexes have also been used as catalysts for the transfer hydrogenation of a variety of simple alkyl and aryl alkyl ketones and good conversions (up to 99 %) were obtained.
