The roles of electrophile and nucleophile are exchanged with respect to those in conventional Friedel–Crafts reactions (arene plus carbenium ion) in these alkylations in the gas phase; an alternative mechanism has thereby been demonstrated–‐an arenium ion reacts with an olefin within the initially formed arenium–olefin complex (see scheme below).
