Kekulene is indeed a “normal” aromatic molecule. This conclusion is reached in a theoretical study in which a number of calculated properties of kekulene and reference compounds such as benzene, phenan-threne, and 1,2:7,8-dibenzanthracene were compared. Structure 1 is the most apt description of this molecule, and claims of superaromaticity can finally be laid to rest.
