Hydride is abstracted from hydridosilanes by trityl tetrakis (bis(3,5-trifluoromethyl)phenyl)borate, Ph3C+B(3,5-(CF3)2C6H3)4-, to yield Ph4CH. The near-quantitative transformation of a trialkylsilane to the fluorosilane can be achieved by using a feebly coordinating solvent such as Ch2Cl2. A nitrile-stabilized silicenium ion (silylnitrilium ion), R3Si(NCC3 H7)+B(3,5-(CF3)2C6H3)4- is developed when a more powerfully coordinating solvent, such as butyronitrile, is employed. NMR(1H, 13C, 11B, 19F, 29Si) spectroscopy, IR spectroscopy and conductivity estimations were used to characterize this salt.
