4,9-DISUBSTITUTED 1,10-ANTHRAQUINONES AND THEIR TAUTOMERISM
Popov, S. I.,Volosenko, V. P.
, p. 983 - 989 (2007/10/02)
The N-alkyl-, N-aryl-, and N-acetyl-substituted 9-imines of 1-hydroxy-4-aminoanthraquinone exist preferentially in the 4,9-diamino-1,10-anthraquinone form.Tautomerism is only observed for diamines with reduced basicity in the nitrogen atom at position 9.
