Nucleogenic silylium cations and their analogs

Radiochemical studies of nucleogenic trivalent cations of the 14th group elements (silicon and germanium) generated by the β-decay of tritium atoms incorporated into organometallic molecules are reviewed. The radiochromatographic analysis of the neutral labeled products of reactions of these cations with various nucleophiles combined with quantum chemical data allowed us to obtain new information about the reactivity and rearrangements of silylium and germylium cations.

Silylium and germylium ions are produced in gas and condensed phases by β-decay of tritium introduced into organometallic molecules and their reactions with nucleophiles are studied.Figure optionsDownload as PowerPoint slideHighlights
► Nucleogenic trivalent silylium and germylium cations generated using the technique of the β-decay.
► The radiochemical study of reactions of silylium ions with benzene demonstrated silylation products.
► In reactions ethyl- and diethylgermilium cations with methyl-tert-butyl ether main products are ethers.
