No abstract

Both protonation of trimethylvinylsilane and addition of Me3Si+ to ethylene in the gas phase produce the cation Me3Si(CH2CH2)+, with 39 kcal mol-1 stabilization energy relative to ethyl cation; however, chloride abstraction from Me3SiCHCICH3 yields a mixture of ions resulting from competing methyl and hydrogen shifts in the nascent silylcarbenium ion.

The hydride ion which can be generated by electron impact on either NH3 or CH4, reacts with alkylsilanes in a flowing afterglow at 0.4 torr total pressure by exclusive addition (reaction A; also occurring with Me4Si, Et2SiH2, and n‐C5H"SiH3).
