  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.
