Definition of hetarenes

Synonymous with heteroarenes.

heteroarenes: 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 -electron system characteristic of aromatic systems and a number of out-of-plane -electrons corresponding to the Hückel rule (4n + 2); an alternative term is hetarenes.
