  Step-by-Step Introduction of Silazane Moieties at Ruthenium: Different Extents of Ru–H–Si Bond Activation

  摘要：

  The coordination of pyridine-2-amino(methyl)dimethylsilane ligands to ruthenium has afforded access to a family of novel complexes that display multicenter Ru-H-Si interactions according to the number of incorporated ligands. The new complexes Ru[kappa-Si,N-(SiMe2)N(Me)(C5H4N)](eta(4)-C8H12)(eta(3)-C8H11) (1), Ru-2(mu-H)(2)(H)(2)[kappa-Si,N-(SiMe2)N(Me)(C3H4N)](4) (2), and Ru(H)[kappa-Si,N-(SiMe2)N(Me)(C5H4N)](3) (3) were isolated and fully characterized. The complexes exhibit different degrees of Si H activation: complete Si H cleavage, secondary interactions between the atoms (SISHA), and re-Si H coordination. Reversible protonation of 3 leading to the cationic complex [RuH{(t/2-HSiMe2)N(Me)kappa-N-(C3H4N)){kappa-Si,N-(SiMe2)N(Me)(C5H4N)}(2)](+)[BAr4F](-) (5) was also demonstrated. The coordination modes in these systems were carefully studied with a combination of X-ray and neutron diffraction analysis, DFT geometry optimization, and multinuclear NMR spectroscopy.

  Fe(acac)(N(κN-C5H4N)Me(SiMe2))(PMe3)3 (5). However, the insertion products Fe(η3-OCOH)(N(κN-C5H4N)Me(SiMe2))(PMe3)3 (6) and Fe(η3-Ph-NCOH)(N(κN-C5H4N)Me(SiMe2))(PMe3)3 (7) were formed through the insertion of the unsaturated bonds into Fe H bond. Complex 6 could also be synthesized through the substitution reaction of 2 with HCOOH. The molecular structures of complexes 2 and 4–7 were determined by single crystal

  摘要用配位体吡啶-2-氨基（甲基）-二甲基硅烷（1）合成氢化甲硅烷基铁。氢化铁（II）FeH（N（κN-C5H4N）Me（SiMe2））（PMe3）3（2）是通过1与Fe（PMe3）4的反应通过一个Si H键的活化和C的配位而获得的吡啶的氮原子。配合物2与卤代烷（CH3I和EtBr）的取代反应提供了配合物FeX（N（κN- ）Me（SiMe2））（PMe3）3（X = I（3）; Br（4））。配合物2与乙酰丙酮反应导致形成Fe（acac）（N（κN- ）Me（SiMe2））（PMe3）3（5）。但是，插入产物Fe（η3-OCOH）（N（κN- ）Me（SiMe2））（PMe3）3（6）和Fe（η3-Ph-NCOH）（N（κN- ）Me（SiMe2） ）（PMe3）3（7）是通过将不饱和键插入Fe H键形成的。配合物6也可以通过2与HCOOH的取代反应来合成。
