摘要：

The formation of adducts of silicenium ions with acetonitrile (N-silylacetonitrilium ions) was elucidated by means of NMR spectroscopy during the hydride abstraction from hydrosilanes by trityl TFPB in CD2Cl2 in the presence of excess acetonitrile. The results indicate that acetonitrile is not a non-nucleophilic solvent suitable for formation of free silicenium ions, but stabilizes the ions by complexation giving tetracoordinate silicon species in solution.
