26.2: Quinones - Chemistry LibreTexts
WEBJul 31, 2021 · Benzoquinones owe their unusual properties as \(\alpha\),\(\beta\)-unsaturated ketones to the ease by which they are transformed to stable aromatic systems. How would these properties change if the quinone were derived from nonaromatic structures, such as cyclobutadiene, cyclooctatetraene, or pentalene?
Quinone - Wikipedia
WEBThe quinones are a class of organic compounds that are formally "derived from aromatic compounds [such as benzene or naphthalene] by conversion of an even number of –CH= groups into –C(=O)– groups with any necessary rearrangement of double bonds", resulting in "a fully conjugated cyclic dione structure".

Benzoquinone - Wikipedia
WEBBenzoquinone (C 6 H 4 O 2) is a quinone with a single benzene ring. There are 2 (out of 3 hypothetical) benzoquinones: 1,3-benzoquinone "does not exist, because its structure would be nonplanar and highly strained", [1] though derivatives are known. An alkylated p -benzoquinone has been found in the rhizomes of Iris kemaonensis. [2]
1,4-Benzoquinone - Wikipedia
WEB1,4-Benzoquinone, commonly known as para-quinone, is a chemical compound with the formula C 6 H 4 O 2. In a pure state, it forms bright-yellow crystals with a characteristic irritating odor, resembling that of chlorine , bleach , and hot plastic or formaldehyde.
Recent advances of quinones as a privileged structure
WEBNov 5, 2021 · In terms of structure, natural quinones are mainly divided into benzoquinone, naphthoquinone, anthraquinone and phenanthraquinone, and benzoquinone is further divided into o-benzoquinone and p-benzoquinone (Fig. 1 A), but the structure of o-benzoquinone is unstable, so most of the natural benzoquinones are p-benzoquinone derivatives.

22.8: Oxidation of Phenols: Benzoquinones - Chemistry LibreTexts
WEBPhenols are rather easily oxidized despite the absence of a hydrogen atom on the hydroxyl bearing carbon. Among the colored products from the oxidation of phenol by chromic acid is the dicarbonyl compound para-benzoquinone (also known as 1,4-benzoquinone or simply quinone); an ortho isomer is also known. These compounds are easily reduced to ...
