1,10-Quinoid structure and prototropic amino-imine tautomerism of α-aminoanthraquinones

Abstract-Structure and amino-imine tautomerism of α- aminoanthraquinones, 1,5- and 1,8-diaminoanthraquinones, as well as 1,4,5-triamino-9,10-anthraquinones was studied. We found that in the study of properties of the compounds prone to tautomeric transformation the tautomeric composition should be taken into account. ©Pleiades Publishing, Ltd., 2012
