The ion–moleculereaction 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
通过放射色谱法在气相和液相中研究了tri代二乙基硅烷的β衰变产生的核型二乙基甲硅烷基阳离子与苯之间的离子-分子反应。具有新生阳离子的二乙基甲硅烷基的二乙基苯基硅烷在气相中产率最低,尽管在液相中产率增加。其他两种甲硅烷基苯基硅烷是二乙基甲硅烷基阳离子重排的产物。通过从头算相关的方法确定了SiC 4 H 11 +系统势能表面上的固定点,并讨论了该系统内可能的重排。
