Recent advances in the gas - phase reaction of aromatics with cationic electrophiles are reviewed. The overall substitution reaction is analyzed in terms of its elementary steps.Mechanistic studies have been focused on the structure and reactivity of covalent and non - covalent ionic intermediates, which display a rich chemistry and provide benchmark reactivity models. Particular attention has been devoted to proton transfer reactions, which may occur intraor intermolecularly in arenium intermediates.

Key words: ELECTROPHILIC REACTION, SUBSTITUTION REACTION, AROMATIC COMPOUNDS, MIGRATION (CHEMICAL)
