Über die Anlagerung von Benzol an Chinon

Abstract: A. D i e S y n t h e s e v o n 2.5-Diphenyl-chinon. Mit Riicksicht auf die eigentiimliche Reaktion von Azo-benzol-Chlorhydrat mit Benzol l) war es interessant zu untersuchen, ob auch C h i n o n der gleichen P h e n y l i e r u n g zugiinglich sei. Es ist tatsiichlich scbon bei gewohnlicher Temperatur mSglich, Benzol mit Hilfe von wasserfreiem Aluminiumchlorid an Chinon anzulagern. Dabei entsteht das schon bekannte 2.5-Dip h e p y l-c h i n o n (I.). Bringt man die Komponenten in trockner Benzol-Losung zusamme… Show more

“…Initially, the arylation of quinones was performed via an AlCl 3 -promoted Friedel-Craft type reaction, where the arylation of para-benzoquinone was explored with aryl substrates through the two sequential additionoxidation steps. [71] Later, this process was re-investigated by Sartori and co-workers in 1993 by taking phenols and benzoquinones coupling partners. [72] AlCl 3 interacts with carbonyls of quinones and subsequently reacts with phenols, leading to aluminum phenoxide quinone adduct (Scheme 29), in which phenoxide gets oxidized and quinone moiety reduced to bis-quinol and forms a carbon-carbon bond.…”

“…Over two decades, scientific communities have given considerable attention to the arylation of quinones to achieve substituted quinones. Initially, the arylation of quinones was performed via an AlCl 3 ‐promoted Friedel‐Craft type reaction, where the arylation of para ‐benzoquinone was explored with aryl substrates through the two sequential addition‐oxidation steps [71] . Later, this process was re‐investigated by Sartori and co‐workers in 1993 by taking phenols and benzoquinones coupling partners [72] .…”

“…Aluminum chloride catalyzes the addition of the system Ar-H to a quinone. For instance, treatment of benzoquinone with benzene and aluminum chloride, followed by oxidation with chromium trioxide, affords a 72 per cent yield of 2,5-diphenylbenzoquinone (117,128).…”
