During the synthesis of [Ru(O2CNiPr2)2(PPh3)2] (1), the [RuCl2(PPh3)3]/NHiPr2/CO2 system produces the intermediates [NH2iPr2][Ru2Cl2(μ-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.

Abstract
During the synthesis of [Ru(O2CNiPr2)2(PPh3)2] (1), the [RuCl2(PPh3)3]/NHiPr2/CO2 system produces the intermediates [NH2iPr2][Ru2Cl2(μ-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.File in questo prodotto:
