10-anthraquinone (DMAQ) from 1,4-naphthoquinone and 2,4‑hexadiene was studied based on a new one-step method developed by the authors for the synthesis of substituted anthraquinones. A solution of high-vanadium heteropoly acid with the empirical formula H17P3Mo16V10O89 (HPA-10) was used as a bifunctional (acid and oxidation) catalyst. It was found that a reaction with 2,4-hexadiene, unlike other methylbutadienes
摘要基于作者开发的一种新的一步法合成取代的蒽醌,研究了由1,4-萘醌和2,4-己二烯合成1,4-二甲基-9,10-蒽醌(DMAQ)的方法。使用经验式为H 17 P 3 Mo 16 V 10 O 89(HPA-10)的高钒杂多酸溶液作为双功能(酸和氧化)催化剂。发现与2,4-己二烯的反应与其他甲基丁二烯不同,不能进行得如此顺利,并且导致形成DMAQ,其二氢衍生物和焦油状产物的混合物。讨论了获得结果的可能原因。
