对络合氢化阴离子[MH(6)](4)(-)(M=Fe和Ru)的制备研究揭示了一些独特的特征。在这里，我们首次制备了一种可溶的均感型氢化钌。例如，Fex(2)和[Ru(eta(4)-1，5-COD)X(2)]，X=氯和溴，在氢气下与PhMgBr溶液反应生成标题化合物。在均相的室温氢化钌制备环己烷和环己烯的情况下，在这些反应中释放的苯更容易被氢化。(1)核磁共振氢谱数据表明，两种络合阴离子在-20.3和-14.7的低频区有氢化物吸收。此外，(1)在Ru和Fe的情况下，M-H的H自旋-晶格弛豫时间(T(1))较长。
A study of the preparations of the complex hydridic anions [MH(6)](4)(-) (M = Fe and Ru) reveals a number of distinctive features. Here a soluble homoleptic ruthenium hydride has been prepared for the first time. For example, both FeX(2) and [Ru(eta(4)-1,5-COD)X(2)], X = Cl and Br, react with PhMgBr solutions under hydrogen to produce the title compounds. The benzene liberated in these reactions is more readily hydrogenated in the case of a homogeneous room temperature ruthenium hydride preparation to both cyclohexane and cyclohexene. The (1)H NMR spectroscopic data show that the two complex anions have hydride absorptions in the low-frequency region, delta -20.3 and -14.7, respectively. Further, (1)H spin-lattice relaxation times (T(1)) for M-H are longer in the case of Ru vs Fe.
