Abstract
The germylation of simple aromatic hydrocarbons has been studied by two different techniques. The Fourier Transform Ion Cyclotron Resonance (FTICR) technique allowed the study of Me 3Ge + transfer equilibria between aromatics and H 2O at 300 K. The ion-molecule reaction of [Me 3Ge + · arene] ions with selected neutrals are accounted for by a σ-complex species, retaining the primary ipso structure, where the germyl group and the former aromatic hydrogen are bound to the same tetrahedral carbon. The free energies of binding of Me 3Ge + to the selected aromatic compounds correlate linearly with the values of the corresponding Me 3Si + reaction with a slope of 0.93. The combined information from the FTICR and radiolytic technique has revealed a mechanistic pattern for the electrophilic aromatic substitution by Me 3Ge + that closely reproduces the corresponding Me 3Si + reaction, the major difference lying in the greater ease of detachment of Me 3Ge + by nucleophilic assistance.
