The dissociative ionizations of p-MeC6H4O[CH2]2SiMe3, MeCH(Cl)SiMe2Cl, and Me[CH2]2SiMe2Cl were studied in the gas phase, experimentally by using tandem mass spectrometric techniques (MS/MS) and computationally by ab initio M.O. methods, revealing a complex scheme of rearrangements that interconvert the resulting isomeric C5H13Si+ ions, including silicenium ions and α- and β-silyl substituted carbocations
在气相中研究了p -MeC 6 H 4 O [CH 2 ] 2 SiMe 3,MeCH(Cl)SiMe 2 Cl和Me [CH 2 ] 2 SiMe 2 Cl的解离电离,采用串联质谱法进行了实验技术(MS / MS)和从头算MO方法进行的计算,揭示了一个复杂的重排方案,可相互转换所得的异构C 5 H 13 Si +离子,包括硅鎓离子以及α-和β-甲硅烷基取代的碳正离子。
