Abstract
Gas-phase reaction of ethylsilylium ions with ethylene was studied by the r adiochemical method. The reaction occurs via excited adduct C4H11Si+ which structurally is a complex of ethylsilylium cation with ethylene. The lifeti me 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.
