Anthraquinones tautomerism: VII. Hydroxy-substituted anthraquinones

open access: yesRussian Journal of Organic Chemistry, 2007
Tautomerism of β-mono-, β,β'-dihydroxyanthraquinones, and their anions was studied for the first time by quantum-chemical and correlation methods. 2-Hydroxyanthraquinone exists exclusively in 9,10-quinoid form, and its ionization involves a tautomeric transformation into 10-oxido-2,9- anthraquinone.

Anthracene and Anthraquinone [PDF]

open access: yesNature, 1921
THE history of anthracene is long and vivid. Discovered amongst the products of coal-tar distillation in 1832, the hydrocarbon played a modest and somewhat commonplace part in the development of structural theory, suddenly blossoming into prominence in 1868, when it was found that alizarin, the twin monarch with indigo of natural colouring matters, is ...
