Solid-State structure and solution reactivity of [(Ph3P)4Ru(H)2] and related Ru(II) complexes used in catalysis: A reinvestigation

X-ray analysis of [(Ph3P)4Ru(H)2] (1) prepared by a literature procedure [ Young, R.; Wilkinson, G. Inorg. Synth. 1990, 28, 337 ] shows that 1 is cocrystallized with PPh3, explaining the previously reported observations of free phosphine in solutions of 1. Lattice PPh3-free forms of 1 have also been obtained, structurally characterized, and found to generate small quantities of uncoordinated PPh3 and another species (A) in solution. Against previous beliefs, however, A is not [(Ph3P)3Ru(H)2] (2), but [(Ph3P)3Ru(H2)(H)2] (3) that forms in the reaction of 1 with adventitious water. This reaction apparently occurs via PPh3 loss from 1 to give 2, followed by H2O coordination, Ru(H)(OH2)/Ru(H2)(OH) rearrangement, H2 loss, and dimerization to give [(Ph3P)4Ru2(H)2(μ-OH)2] (4). The H2 thus produced is trapped with 2 to give 3. Complexes 3·0.5C6H6, 3·2THF, 4·2H2O, [(Ph3P)3Ru(N2)(H)2] (5), and [(Ph3P)2(H)Ru(μ-H)3Ru(PPh3)3]·0.5THF (6·0.5THF) have been structurally characterized for the first time. Also for the first time, a single-crystal X-ray diffraction study of the long-known [(Ph3P)4RuCl2] (7) has been performed to finally demonstrate that 7 is, in fact, [(Ph3P)3RuCl2]·PPh3, precisely as proposed by Hoffman and Caulton as early as 1975 [ Hoffman, P.R.; Caulton, K.G. J. Am. Chem. Soc. 1975, 97, 4221 ].

Synthesis of ruthenium and iridium polyhydride complexes under conditions of phase transfer catalysis

The chlorohydrido complexes of ruthenium (Ph3P)3Ru(H)Cl and iridium (i-Pr3P)2Ir(H)Cl2 react smoothly with H2 (1 atm, 20 deg C) in a 50percent NaOH/benzene two-phase system in the presence of triethylbanzylammonium chloride as a phase transfer catalyst to form polyhydride complexes (Ph3P)3Ru(H2)(H)2 (1) and (i-Pr3P)2IrH5 (2), respectively, in quantitative yields.

New N,N-diisopropylcarbamato complexes of ruthenium(II) as catalytic precursors for olefin hydrogenation

During the synthesis of [Ru(O2CNiPr2) 2(PPh3)2] (1), the [RuCl2(PPh 3)3]/NHiPr2XCO2 system produces the intermediates [NH2iPr2][Ru2Cl 2(H-Cl)3(PPh3)4] (2) and [RuCl(O2C-NiPr2)(PPh3)3] (3) which have been isolated and fully characterised. Compound 2 contains the dinuclear anionic triply chloride-bridged rathenium(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.
