## heteroarenes

https://doi.org/10.1351/goldbook.H02791
@H02798@ formally derived from @A00435@ 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 ($$4\ n+2$$); an alternative term is @H02787@.
