  heterolytic activation of the Si–H bond. The molecular structure of a new example of such an adduct was resolved by X-ray diffraction analysis. Theoretical considerations support a donor–acceptor [C,N}Cp*IrIII-H]→[SiEt3]+ (C,N} = benzo[h]quinolinyl) formulation where the cationic silyl moiety acting as a Z ligand binds both Ir and H centers. Under the conditions of the catalysis, the latter adduct is assumed

  A catalytic synthesis of deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2 is reported that allows their facile generation in a 3–4 g scale, utilizing D2 (0.5 bar) as the hydrogen isotope source and low catalyst loadings (0.01 mol%). The catalyst precursor is the rhodium (III) complex 1, which contains a (η5-C5Me5)Rh cation stabilized by coordination to a cyclometallated phoshine PMeXyl2 (Xyl = 2,6-C6H3Me2)

  据报道，氘代硅烷 SiEt3D、SiMe2PhD 和 SiPh2D2 的催化合成允许它们以 3-4 g 的规模轻松生成，利用 D2 (0.5 bar) 作为氢同位素源和低催化剂负载 (0.01 mol%)。催化剂前体是铑 (III) 络合物 1，它包含 (η5-C5Me5)Rh 阳离子，通过与环金属化膦 PMeXyl2 (Xyl = 2,6-C6H3Me2) 配位而稳定。同样的配合物也是各种酮、醛和 α,β-不饱和腈的 CO 和 C≡N 键的氢化硅烷化的活性催化剂。因此，这两种特性的组合允许开发用于这些底物的氘代硅烷化的简单且熟练的单烧瓶、两步程序。版权所有 © 2011 John Wiley & Sons, Ltd.

  The ionic iridacycle [(2-phenylenepyridine-kappa N,kappa C)-IrCp*(NCMe)][BArF24] ([2][BArF24]) displays a remarkable capability to catalyze the O-dehydrosilylation of alcohols at room temperature (0.4 x 10(3) < TON < 10(3), 8 x 10(3) < TOFi < 1.9 x 10(5) h(-1) for primary alcohols) that is explained by its exothermic reaction with Et3SiH, which affords the new cationic hydrido-Ir(III)-silylium species [3][BArF24]. Isothermal calorimetric titration (ITC) indicates that the reaction of [2][BArF24] with Et3SiH requires 3 equiv of the latter and releases an enthalpy of -46 kcal/mol in chlorobenzene. Density functional theory (DFT) calculations indicate that the therrnochemistry of this reaction is largely dominated by the concomitant bis-hydrosilylation of the released MeCN ligand. Attempts to produce [3][BF4] and [3][OTf] salts resulted in the formation of a known neutral hydrido-iridium(III) complex, i.e. 4, and the release of Et3SiF and Et3SiOTf, respectively. In both cases formation of the cationic p-hydrido-bridged bis-iridacyclic complexes [5][BF4] and [5][OTf], respectively, was observed. The structure of [5][OTf] was established by X-ray diffraction analysis. Conversion of [3] [BArF24] into 4 upon reaction with either 4-N,N-dimethylaminopyridine or [nBu(4)][OTf] indicates that the Ir center holds a +III formal oxidation state and that the Et3Si+ moiety behaves as a Z-type ligand according to Green's formalism. [3][BArF24], which was trapped and structurally characterized and its electronic structure investigated by state-of-the-art DFT methods (DFT-D, EDA, ETS-NOCV, QTAIM, ELF, NCI plots and NBO), displays the features of a cohesive hydridoiridium(III)-> silylium donor-acceptor complex. This study suggests that the fate of [3](+) in the O-dehydrosilylation of alcohols is conditioned by the nature of the associated counteranion and by the absence of Lewis base in the medium capable of irreversibly capturing the silylium species.
