Preferred Label : heteroarenes;
IUPAC definition : heterocyclic compounds formally derived from arenes by replacement of one or more
methine (–C ) and/or vinylene (–CH CH–) groups by trivalent or divalent heteroatoms,
respectively, in such a way as to maintain the continuous π-electron system characteristic
of aromatic systems and a number of out-of-plane π-electrons corresponding to the
Hückel rule (4n 2); an alternative term is hetarenes.;
