  The Osmium–Silicon Triple Bond: Synthesis, Characterization, and Reactivity of an Osmium Silylyne Complex

  摘要：

  The first silylyne complex of a metal beyond group 6, [Cp*((Pr3P)-Pr-i)(H)Os Si(Trip)][HB(C6F5)(3)], was prepared by a new synthetic route involving hydride abstraction from silicon. NMR and DFT computations support the presence of a silylyne ligand, and NBO and ETS-NOCV analysis revealed the nature of this Os-Si interaction as a triple bond consisting of a covalent sigma bond and two strong pi back-donations. The discovery of this complex allowed observations of the first cycloadditions involving a silylyne complex, and terminal alkynes are shown to react via C-H bond additions across the Os Si bond.

  Reaction of. Cp*((Pr2MeP)-Pr-i)RuCl (1) with 0.5 equiv of Mg(CH2Ph)(2)(THF)(2) afforded the benzyl complex Cp*((Pr2MeP)-Pr-i)Ru(eta(3)-CH2Ph) (2). Complex 2 readily reacted with, Primary silanes H3SiR (R = trip, dmp, Mes(F); trip = 2,4,6-Pr-i(3)-C6H2, dmp = 2,6-Mes(2)-C6H3, Mes(F) = 2,4,6-(CF3)(3)-C6H2) to liberate toluene and afford hydrogen-substituted silylene complexes Cp*((Pr2MeP)-Pr-i)(H)Ru=SiH(R) (R = trip, 3; dmp, 4; Mes(F), 5]. Complexes 3-5 exhibit characteristic SiH H-1 NMR resonances downfield of 8 ppm and very small (2)J(SiH) coupling constants (8-10 Hz). The solid state structures of complexes 3 and 5 feature short Ru-Si distances of 2.205(1) and 2.1806(9) angstrom, respectively, and planar silicon centers. In addition, the silylene complex Cp*((Pr2MeP)-Pr-i)(H)Ru=SiPh(trip) (6) and the unusual, chlorine-substituted species Cp*((Pr2MeP)-Pr-i)(H)Ru=SiCl(R) [R = trip, 7; dmp, 8] were prepared. Hydrogen-substituted ruthenium germylene complex Cp*((Pr2MeP)-Pr-i)(H)Ru=GeH(trip) (9) was prepared similarly by reaction of 2 with tripGeH(3). Complex 9 is the first structurally characterized ruthernium germylene complex and has a remarkably short Ru-Ge distance of 2.2821(6) angstrom. Complex 9 adds H2O across its Ru=Ge bond to give Cp*((Pr2MeP)-Pr-i)(H)(2)RuGeH(OH)(trip) (10).
