Preferred Label : arenium ions;
IUPAC definition : cations derived formally by the addition of a hydron or other cationic species to
any position of an arene, e.g. c6h71, benzenium. the term includes: arenium s-adducts
(wheland intermediates) (which are considered to be intermediates in electrophilic
aromatic substitution reactions) and other cyclohexadienyl cations.arenium p-adducts,
such as: [s-adduct (sigma-adduct), p-adduct (pi-adduct)].;
