摘要:

A study was made of the solvent effects observed in the absorption spectra of N-(2-hydroxy-1-naphthylidene)anilines, N-(2-hydroxybenzylidene)amines and N-(4-hydroxybenzylidene)aniline in various solvents. It was established that the logarithm of the constant describing the equilibrium enol ⇔ keto tautomer correlates closely with the parametersENTand BKTcharacteristic of the acidity or basicity of the solvents.
