Oxepin is an oxygen-containing heterocycle consisting of a seven-membered ring with three double bonds. It exists as an equilibrium mixture with benzene oxide. The oxepin–benzene oxide equilibrium can easily be shifted to one extreme or the other in compounds with this core depending what substituents are present.^[1] This compound is not aromatic.
