Synthesis, Structure, and Reactivity of Ruthenium‐Indane Complexes with diphosphine ligand

Abstract

Ruthenium‐indane complex, fac‐[Ru(NCMe)3(CO)2(InCl3)] 1Cl reacted with 0.5 equiv. of dppe/dppp to afford dinuclear ruthenium‐indane complexes linked by diphosphine ligand, [Ru(NCMe)2(CO)2(InCl3)]2(η2,μ2‐Ph2P(CH2)nPPh2) (n = 2: 3, 3: 4). On the other hand, the reaction of fac‐[Ru(NCMe)3(CO)2(InCl3)] with 1 equiv. of dppp afforded the corresponding chelate ruthenium(0) indane complex, [Ru(NCMe)(CO)2(InCl3)(dppp)] 5. In the case of dppm, a chelate complex [Ru(NCMe)(CO)2(InCl3)(dppm)] 6 was formed via the dinuclear Ru complex [Ru(NCMe)2(CO)2(InCl3)]2(η2,μ2‐Ph2PCH2PPh2). Complexes 1Cl, 5, and 6 showed a catalytic activity for double‐hydrosilylation of acetonitrile. Complexes 3–6 were fully characterized using NMR measurements, elemental analyses, and the structures of 1Cl, 3, 5, and 6 were determined by X‐ray crystallography.
