dc.description.abstractThe starting material N,N '-bis(diphenylphosphino) ethane-1,2-diamine (1) was prepared for the first time in this study by a one-step reaction of 1,2-ethylenediamine with one equivalent of diphenylchlorophosphine. The reaction of 1 with either [Ru(p-cymene)(mu-Cl)Cl](2) or [Ru(benzene)(mu-Cl)Cl](2) afforded a series of novel bridged binuclear complexes of [C2H4-{NHPPh2-Ru(benzene)Cl-2}(2)], 1a and [C2H4-{NHPPh2-Ru(p-cymene)Cl-2}(2)], 1b, respectively. All newly synthesized complexes were comprehensively characterized using various analytical and spectroscopic techniques. H-1-, C-13-, P-31{H-1} NMR, (HH)-H-1-H-1 COSY or (HC)-H-1-C-13 HETCOR correlation experiments were employed to validate the spectral assignments. Both complexes are appropriate catalyst precursors for transfer hydrogenation of acetophenone derivatives. In particular, the complex [C2H4-{NHPPh2-Ru(benzene)Cl-2}(2)], referred to as 1a, demonstrates outstanding catalytic efficiency, by producing the relevant alcohols in 99 % conversion at 82 degrees C (TOF similar to 1200 h(-1)) in 5 min, outperforming analogous complexes in transfer hydrogenation reactions. Furthermore, the chemical characterizations, electronic transitions, and electrochemical properties of the Ru(II) complexes were systematically investigated by experimental methods.
