During the conversion, an even\u003c\/p\u003e\u003cp\u003enumber of (CH) groups are oxidised into (C=O) groups and necessary double\u003c\/p\u003e\u003cp\u003ebonds are rearranged to get fully conjugated cyclic dione structure1. Apart from\u003c\/p\u003e\u003cp\u003ethis, organic molecules such as phenols and catechols having electron donating\u003c\/p\u003e\u003cp\u003esubstituents are easily oxidized to quinones. The electron donating substituents\u003c\/p\u003e\u003cp\u003eincrease the nucleophilicity of the ring and contributes to the large redox\u003c\/p\u003e\u003cp\u003epotential needed to break the aromaticity (quinones are conjugated but not\u003c\/p\u003e\u003cp\u003earomatic).\u003c\/p\u003e\u003cp\u003eMany natural and artificial colouring substances (dyes and pigments) are quinone\u003c\/p\u003e\u003cp\u003ederivatives. They are next to azo dyes in importance as dyestuffs with particular\u003c\/p\u003e\u003cp\u003eemphasis on blue colours. Alizarin {1,2-dihydroxy-9,10-anthraquinone} (8), \u003c\/p\u003e\u003cp\u003eextracted from the madder plant, was the first natural dye to be synthesized from\u003c\/p\u003e\u003cp\u003eanthracene. This was used as the prominent red dye for dyeing textile fabrics.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Sanjay S\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independent Author\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 03\/03\/2023\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 170\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.57lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.39d\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9781805247951\u003c\/p\u003e","brand":"Independent Author","offers":[{"title":"Paperback","offer_id":40828207464563,"sku":"9.78181E+12","price":34.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9255\/0515\/products\/img_4cfee3c4-c1aa-49eb-98b8-6a746dcbbca7.jpg?v=1684327273","url":"https:\/\/bookstorenmore.com\/en-de\/products\/studies-on-new-aspects-of-quinone-chemistry-9781805247951","provider":"Bookstore N More","version":"1.0","type":"link"}
