  2. Catechol - Wikipedia

    en.wikipedia.org/wiki/Catechol

    Catechol (/ ˈ k æ t ɪ tʃ ɒ l / or / ˈ k æ t ɪ k ɒ l /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2. It is the ortho isomer of the three isomeric benzenediols .

  3. Dihydroxybenzenes - Wikipedia

    en.wikipedia.org/wiki/Dihydroxybenzenes

    There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]

  4. 1,2-Benzoquinone - Wikipedia

    en.wikipedia.org/wiki/1,2-Benzoquinone

    1,2-Benzoquinone, also called ortho-benzoquinone, is an organic compound with formula C 6 H 4 O 2. It is one of the two isomers of quinone , the other being 1,4-benzoquinone . It is a red volatile solid that is soluble in water and ethyl ether .

  5. Arene substitution pattern - Wikipedia

    en.wikipedia.org/wiki/Arene_substitution_pattern

    Fractional crystallisation can be used to obtain pure para product, relying on the principle that it is less soluble than the ortho and thus will crystallise first. Care must be taken to avoid cocrystallisation of the ortho isomer. [2] Many nitro compounds' ortho and para isomers have quite different boiling points. These isomers can often be ...

  6. Ortho effect - Wikipedia

    en.wikipedia.org/wiki/Ortho_effect

    There are three main ortho effects in substituted benzene compounds: Steric hindrance forces cause substitution of a chemical group in the ortho position of benzoic acids become stronger acids. Steric inhibition of protonation caused by substitution of anilines to become weaker bases, compared to substitution of isomers in the meta and para ...

  7. Catechol oxidase - Wikipedia

    en.wikipedia.org/wiki/Catechol_oxidase

    The catalytic cycle begins with the catechol oxidase in its native oxidized Cu(II)-Cu(II) state with a coordinated hydroxide ion bridging the two copper centers. As catechol enters the active site, a proton is abstracted from one of the alcohols. The catechol coordinates with a Cu(II) center in a monodentate fashion, displacing one of the ...

  9. Cis-1,2-dihydrobenzene-1,2-diol dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Cis-1,2-dihydrobenzene-1,2...

    Thus, the two substrates of this enzyme are cis-1,2-dihydrobenzene-1,2-diol and NAD +, whereas its 3 products are catechol, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor.
