Template:Chembox Footer/trackingTemplate:Short description
Oxepine 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 oxepine isomer, an orange liquid.[2]
In nature, oxepine is an intermediate in the oxidation of benzene by the cytochrome P450 (CYP).[3] Other arene oxides are metabolites of the parent arene.
Benzene oxides are produced in the laboratory from dehydrohalogenation of the corresponding dihaloepoxide:[4]
