Radiochemical study of the reaction between the diethylsilylium cation and benzene in gas and liquid phases: experimental and theoretical evidence for rearrangements of the diethylsilylium cation

The ion–molecule reaction between the nucleogenic diethylsilylium cation generated by the β-decay of the tritiated diethylsilane and benzene was studied by the radiochromatographic method in the gas and liquid phases. Diethylphenylsilane possessing the diethylsilyl group of the nascent cation has th...

Summary:The ion–molecule reaction between the nucleogenic diethylsilylium cation generated by the β-decay of the tritiated diethylsilane and benzene was studied by the radiochromatographic method in the gas and liquid phases. Diethylphenylsilane possessing the diethylsilyl group of the nascent cation has the lowest yield in the gas phase, although in the liquid phase the yield increases. Two other silylphenylsilanes are products of rearrangement of the diethylsilylium cation. The stationary points on the potential energy surface of the SiC 4H 11 + system were located by the ab initio correlated methods and the plausible rearrangements within this system are discussed.
