Gas-phase reaction of ethylsilylium ions with ethylene was studied by the radiochemical method. The reaction occurs via excited adduct C4H11Si+ which structurally is a complex of ethylsilylium cation with ethylene. The lifetime of this complex is long enough for the isotope exchange between tritium atoms of the cation and a proton of ethylene, as well as the isomerization of ethylsilylium cation to dimethylsilylium to occur. Decomposition of the complex results in predominant formation of labeled ethylene.
Ion-molecule reactions of monosubstituted ethylsilylium ions with trimethyl(tert-butylamino)silane in the gas phase

, p. 1233 - 1236 (2007/10/03)
Reaction of nuclear-chemically generated ethylsilylium ions with trimethyl(rert-butylamino)silane in the gas phase was studied. In the course of reaction the ethylsilylium ion completely isomerizes into the dimethylsilylium ion. Experiments show that the pathway involving proton transfer practically is not realized, in contrast to the reactions of carbenium ions with amines.
Ion-molecular reactions of free ethylsilicenium ions with alcohols in the gas phase

, p. 885 - 888 (2007/10/03)
Ion-molecular reactions of free ethylsilicenium ions with methanol and isobutanol in the gas phase were studied radiochemically. Within the reaction time the ethylsilicenium ion completely isomerizes into the dimethylsilicenium ion. The reaction mechanism was suggested.
