Tautomeric equilibria of para- and ana-quinoid forms of 5-hydroxy-1,4-naphthoquinone-4-imines in solutions were studied by UV and H-1 NMR spectroscopy. The one-form is stabilized by electron-donating substituents at positions 2 and 8 and at nitrogen atom and by electron-withdrawing, substituents at position 6.
