Geçifl metal katalizörlerinin transfer hidrojenasyon reaksiyonuyla organik substratlara hidrojen katılmasıveya çıkarılması önemli bir sentetik araçtır. Bu amaçla, N3,N3'-di-2-hidroksibenziliden-[2,2']bipiridinil3,3'-diamin bilefliğinden elde edilen bir P-O ligandı olan N3,N3'-di-2- difenilfosfino benziliden-[2,2']bipiridinil3,3'-diaminin bir dizi metal kompleksi sentezlendi. N3,N3'-di-2- difenilfosfino benziliden-[2,2']bipiridinil3,3'-diaminin [Ru η-benzen µ-Cl Cl] yada [Ru η-p-simen µ-Cl Cl]2 ile reaksiyonu köprülü ve ikiçekirdekli [CH16N4{OPPh2-Ru η6-benzen Cl2}2] 1 ve [Ckomplekslerini vermektedir. Ru II -bisfosfinit kompleksleri ayrıca basit birçok alkil ve aril alkil ketonuntransfer hidrojenasyonunda katalizör olarak kullanıldı ve iyi düzeyde % 99'a kadar dönüflümler eldeedildi
The ability of transition metal catalysts to add or remove hydrogen from organic substrates by transferhydrogenation process is a valuable synthetic tool. For this aim, a series of metal complexes with a P-Oligand, 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 η6-benzene µ-Cl Cl]2 or [Ru η6p-cymene µ-Cl Cl]2 gave bridged dinuclear complexes [C24H16N4{OPPh2-Ru η6-benzene Cl2}2] 1 and[C24H16N4{OPPh2-Ru η6-p-cymene Cl}2] 2, respectively. Ru II -bisphosphinite complexes have also beenused as catalysts for the transfer hydrogenation of a variety of simple alkyl and aryl alkyl ketones and goodconversions up to 99 % were obtained
