摘要

钌-茚配合物 fac-[Ru(NCMe)3(CO)2(InCl3)] 1Cl 与 0.5 等量的 dppe/dppp 反应，得到由二膦配体连接的双核钌-茚配合物 [Ru(NCMe)2(CO)2(InCl3)]2(η2,μ2-Ph2P(CH2)nPPh2)（n = 2：3，3：4）。另一方面，面-[Ru(NCMe)3(CO)2(InCl3)]与 1 等量的 dppp 反应得到相应的螯合钌（0）茚络合物 [Ru(NCMe)(CO)2(InCl3)(dppp)]5。在 dppm 的情况下，通过二核 Ru 复合物 [Ru(NCMe)2(CO)2(InCl3)]2(η2,μ2-Ph2PCH2PPh2)，形成了螯合物 [Ru(NCMe)(CO)2(InCl3)(dppm)] 6。络合物 1Cl、5 和 6 对乙腈的双氢硅烷化具有催化活性。利用核磁共振测量和元素分析对络合物 3-6 进行了全面表征，并通过 X 射线晶体学确定了 1Cl、3、5 和 6 的结构。

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

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{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.
