  Synthesis, structure, and reactivity of disilanes containing one neutral [4+2]-coordinate silicon center

  摘要：

  [4+2]-Coordinate disilanes containing two 8-dimethylamino-1-naphthyl (8-Me2N-1-Np) groups on the same silicon atom, (8-Me2N-1-Np)(2)XSi-SiMe3, where X = F, OH, OEt. and H, are prepared. The X-ray structures of the two derivatives, X = F and OH, show that one of the coordinated dimethylamino groups is anti to the electronegative X group, while the other is anti to the trimethylsilyl group. The [4 + 2]-coordinate disilanes (X = F or OEt) are found to be thermally stable under these conditions such that the corresponding (4 + 1]-coordinate disilanes (8-Me2N-1-Np)XMeSi-SiMePh2 (X = F or OEt) readily undergo degradation. In the presence of Pd(PPh3)(4) as a catalyst, the [4 + 2]-coordinate disilane (X = F) undergoes degradation to generate naphthylsilane (8-Me2N-1-Np)-SiMe3, the reaction pathway being different from that of the [4 + 1]-coordinate disilane (X = F) which affords the fluorosilane, F-SiMePh2.

• CMe3SiX3 and SiMe3SiX3 (X=H, F, Cl, Br, I): a combined ab initio and vibrational spectroscopic study
  作者：Robert Zink、Karl Hassler

  DOI：10.1016/s1386-1425(98)00189-9

  日期：1999.2

  The infrared and Raman vibrational spectra of the tert-butylsilanes CMe3SiX3 and disilanes SiMe3SiX3 (X = H, F, Cl, Br, I) have been measured and assigned with the help of normal coordinate analyses and potential energy distribution analyses employing ab initio optimized geometries and ab initio symmetry force constants. Scaled theoretical SiX and SiSi force constants are smaller than values estimated by extrapolation from spectroscopic force constants of related disilanes. The synthesis of the novel compound SiMe3SiI3 and the residual disilanes SiMe3SiX3 (X = H, F, Cl, Br) is described. (C) 1999 Elsevier Science B.V. All rights reserved.
