Abstract

The interaction of triphenylphosphine, -arsine and -stibine with hydrated ruthenium trichloride in methanol leads to a variety of complexes such as [RuCl2(PPh3)4], [RuCl2(PPh3)3], [RuCl3(PPh3)2CH3OH], [RuCl3(AsPh3)2CH3OH] and [RuCl2(SbPh3)3]. The corresponding bromo complexes are also described. New mono and dicarbonyl complexes of ruthenium (II) and (III) have also been prepared by the interaction of Ph3P, Ph3As, Ph3Sb, pyridine etc., with a carbonyl-containing solution. Complexes of type cis and trans-[RuCl2(CO)2L2], [RuCl2(CO)L3] and [pyH][RuCl4COpy] are described.

    The work presented in those studies largely focused on transition metal complexes supported by polydentate ligands. It is somewhat surprising, however, that dichlorotris(triphenylphosphine)ruthenium(II), RuCl2(PPh3)3 [12–14], which is a precursor to catalysts for homogeneous hydrogenation of olefins[15] and for olefin metathesis [16,17], has very few reports on its reactivity with hydrazines. We suspect that this is due to the complex solution behavior of the material, specifically the lability of the triphenylphosphine ligands [18].
