  Synthesis of Oxo- and Sulfido-Bridged Germanium−Ruthenium Complexes and Reactions on the Chalcogenido Bridges

  摘要：

  A series of heterodinuclear germanium-ruthenium complexes having sulfido/oxo bridges, Dmp(Dep)Ge(mu-E-1)(mu-E-2)Ru(eta(6)-arene) (E-1, E-2 = S, O; arene) benzene, p-cymene; Dmp = 2,6-dimesitylphenyl, Dep) 2,6-diethylphenyl) were synthesized by the reaction of [Ru(eta(6)-arene)Cl-2](2) and the corresponding diarylgermanedichalcogenoles, Dmp(Dep)Ge((EH)-H-1)((EH)-H-2). The reaction with tertiary phosphines gave the corresponding adducts Dmp(Dep)Ge(mu-S)(mu-E)Ru(PR3) (E = S, O; R = Ph, Et), in which the arene ligand on the ruthenium was replaced by a mesityl group of Dmp. When Dmp(Dep)Ge(mu-S)(2)Ru(PPh3) was treated with the Bronsted acids H(OEt2)(2)BAr4F and HOTf, a sulfido bridge was protonated to afford [Dmp(Dep)Ge(mu-S)(mu-SH)Ru(PPh3)]X (X = BAr4F, OTf). Likewise, the methylation reaction with Me3OBF4 proceeded at a mu-S, generating [Dmp(Dep)Ge(mu-S)(mu-SMe)Ru(PPh3)](BF4). On the other hand, protonation of Dmp(Dep)Ge(mu-S)(mu-O)Ru(PPh3) gave a mu-OH complex, [Dmp(Dep)Ge(mu-S)(mu-OH)Ru(PPh3)](+), while the analogous methylation afforded the cationic mu-SMe complex [Dmp(Dep)Ge(mu-SMe)(mu-O)Ru(PPh3)](+).

• Dihydrogenactivation by sulfido-bridged dinuclear Ru/Ge complexes: insight into the [NiFe] hydrogenase unready state

  日期：——

  A S/SH bridged hetero-dinuclear Ru/Ge complex cation reacted with H(2) to afford the mu-S/mu-H complex. The reaction was considerably slower compared to that of the mu-S/mu-OH complex. Thus, the mu-S/mu-SH and mu-S/mu-OH complexes might provide models for the unready and ready states, respectively, of [NiFe] hydrogenase.

  AS / SH桥接异核Ru / Ge络合物阳离子与H（2）反应，提供mu-S / mu-H络合物。与mu-S / mu-OH配合物相比，反应明显慢。因此，mu-S / mu-SH和mu-S / mu-OH复合物可能分别为[NiFe]氢化酶的未就绪和就绪状态提供模型。
