1,4-Dioxane-1,4-diium
c) Cations formed by unspecified addition of a hydron to an aromatic system are also named by attaching the ending ... ium to the name of the
parent. These so-called arenium ions correspond essentially to the TIcomplexes of electrophilic aromatic substitution. (For specific addition
ofhydrons to such systems see d.)

The same procedure is applicable for depicting hydron addition to a saturated hydrocarbon as effected by superadds. The resulting "nonclassical" carbocations are subsumed under the class name carbonium ions.
