Oxepin is an oxygen-containing heterocycle consisting of a seven-membered ring with three double bonds. The parent C6H6O exists as an equilibrium mixture with benzene oxide. The oxepin–benzene oxide equilibrium is affected by the ring substituents.[1] A related dimethyl derivative exists mainly as the oxepin isomer, an orange liquid.[2]

Formation and selected reactions of benzene oxide.

Oxepin is an intermediate in the oxidation of benzene by the cytochrome P450.[3] Other arene oxides are metabolites of the parent arene.
