  Synthesis, characterization and reactivity of Cp(C2H4) iMe2) ; a model compound of selective double silylation

  摘要：

  o-Bis(dimethylsilyl)benzene (1) reacts with cyclopentadienylbis(ethylene)cobalt at room This reaction results in overall double Si-H activation, generating the disilacobaltacycle complex Cp(C2H4)Co(o-Me2SiC6H4SiMe2) (3). Complex 3 was characterized by X-ray diffraction. 1,2,4,5-Tetrakis(dimethylsilyl)benzene reacts with CpCo(C2H4)(2) to give 4,12,6,10-benzo-1,1,3,3,7,7,8,9,9-nonamethyl-1,3-disilacobaltacycle-7,8-disilacyclopent-6-ene (4). Complex 4 was characterized by X-ray diffraction and found to contain a 6,10-benzo-7,7,8,9,9-pentamethyl-7,9-disilacyclopent-6-ene via 1,1-double silylation.

  solvent under a nitrogen atmosphere afforded the dinuclear bis(silyl)iron complexes [(η6-arene)Fe(Me2SiC6H4SiMe2)]2(μ-η1:η1-N2) (1), which have an end-on-bound bridging dinitrogen ligand. The dinitrogen unit easily dissociated from the Fe center to generate the mononuclear (η6-arene)FeII(Si)2L or (η6-arene)FeIV(Si)2H2 complexes by the reactions with CO, PPh3, and H2.

• Disilametallacycles as a Platform for Stabilizing M(II) and M(IV) (M = Fe, Ru) Centers: Synthesis and Characterization of Half-Sandwich Complexes and Their Application to Catalytic Double Silylation of Alkenes and Alkynes

  A series of group 8 half-sandwich disilametallacycles, (eta(6)-arene)M-II(Me2SiC6H4SiMe2)L and (eta(6)-arene)M-IV(H)(2)(Me2SiC6H4SiMe2) (M = Fe, Ru) in the formal oxidation states of M(II) and M(IV) were synthesized and characterized. Both the M(II) and the M(IV) oxidation states were effectively stabilized by the disilametallacycle skeleton, and facile interconversion between (eta(6)-arene)M-II-dinitrogen, (eta(6)-arene)M-II-carbonyl, and (eta(6)-arene)M-IV-dihydride complexes bearing a disilaferracycle framework was accomplished. These M(II) and M(IV) complexes can easily generate coordinatively unsaturated 16e disilametallacycles, (eta(6)-arene)M-II(Me2SiC6H4SiMe2), by dissociation of L or H-2, and stoichiometric and/or catalytic double silylation of alkenes and alkynes was realized thorough this 16e intermediate.
