| Abstract: | The tautomeric equilibrium of phenylazonaphthols was investigated by the HMO method and by IR spectroscopy. It was found that in the case of 4-phenylazo-1-naphthol the thermodynamic stability of the tautomers was approximately the same, in the case of 1-phenylazo-2-naphthol the naphthoquinone hydrazone tautomer was substantially more stable. |
