It was shown by 13C NMR that a redistribution of the bonds with partial localization of the 1,5- and 1,10-anthraquinonoid structures occurs during the transition from 1,5-diamino(dihydroxy)- and 1-amino(hydroxy)-9,10-anthraquinones respectively to their borate complexes.For this reason the boroacetates and fluoroborates of 1,5-dihydroxyanthraquinonones, 1-aminoanthraquinones, their N-alkyl and N-aryl derivatives, and 1,5-dihydroxyanthraquinone are capable of entering into amination under the influence of aromatic amines with substitution of the hydrogen atom at position 4 under mild conditions with the participation of atmospheric oxygen as oxidizing agent
