  摘要：

  Trityl tetrakis[bis(3,5-trifluoromethyl)phenyl]borate, Ph3C+B[3,5-(CF3)2C6H3]4-, abstracts hydride from hydridosilanes, producing Ph3CH. Use of a weakly coordinating solvent (i.e., CH2Cl2) results in near-quantitative conversion of a trialkylsilane to the fluorosilane. When a more strongly coordinating solvent, e.g., butyronitrile, is used, a nitrile-stabilized silicenium ion (silylnitrilium ion), R3Si(NCC3H7)+B[3,5-(CF3)2C6H3]4-, is formed. This salt was characterized by NMR (H-1, C-13, B-11, F-19, Si-29) Spectroscopy as well as IR spectroscopy and conductivity measurements. The reactions of this species with simple nucleophiles are also reported.
