Tautomerism of metal complexes with 1,8-dihydroxy-3-R1-6-R 2-9,10-anthraquinones, quantum-chemical, and correlation methods were found to be determined by tautomeric 9

Competing tautomeric transformations and the structure of 1-(alkyl,aryl)amino-4-hydroxyanthraquinonesKeto-enol and amine-imine tautomerism and equilibria with trans-conformers are characteristic of 1

Tautomerism of the natural 1,8-dihydroxy-9,10-anthraquinones chrysophanol, aloe-emodin, and rhein tautomers are observed in certain media. As a rule, these compounds in alkaline solutions form 1

Theoretical and experimental study of imine-enamine tautomerism of condensation products of propanal with 4-aminobenzoic acid in ethanol tautomeric forms of the reduced compounds in solution was established. The tautomeric equilibrium
