摘要：

During the synthesis of [Ru(O2CNiPr2)(2)(PPh3)(2)] (1), the [RuCl2(PPh3)(3)]/NHiPr(2)/CO2 system produces the intermediates [NH(2)iPr(2)][Ru2Cl2(mu-Cl)(3)(PPh3)(4)] (2) and [RuCl(O2CNiPr2)(PPh3)(3)] (3) which have been isolated and fully characterised. Compound 2 contains the dinuclear anionic triply chloride-bridged ruthenium(II) species. Compound 3 is mononuclear, the octahedral ruthenium centre being coordinated to the bidentate carbamato ligand. The reactions of compounds 1 and 3 with dihydrogen have been studied at room temperature and atmospheric pressure with respect to their catalytic hydrogenation of 1-octene.
