A diazaquinone is a chemical compound that has an heterocyclic aromatic core including two consecutive doubly-bonded nitrogen atoms Шаблон:Chem2, with the two Шаблон:Chem2 carbon units adjacent to the nitrogens replaced by carbonyl (ketone) groups Шаблон:Chem2. These carbon and nitrogen atoms then comprise a diacyl diimide unit, Шаблон:Chem2.[1]

Two canonical examples are 3,6-pyridazinedione (a quinone of pyridine), emerald-green; and 1,4-phthalazinedione (a quinone of phthalazine) a green crystalline solid (both soluble in acetone and stable at -77 °C).[1]

The name was proposed by Thomas J. Kealy in 1962.[1]
