Synthesis, Structure, and Reactivity of Ruthenium‐Indane Complexes with Diphosphine Ligand

Abstract

AbstractRuthenium‐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{μ2‐Ph2P(CH2)nPPh2}] (n=2: 3, 3: 4). On the other hand, the reaction of fac‐[Ru(NCMe)3(CO)2(InCl3)] 1Cl 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(μ2‐dppm)]. Complexes 1Cl, 5, and 6 showed a catalytic activity for double‐hydrosilylation of MeCN. 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.
