1,2,4-Triazoles. IV. Tautomerism of 3,5-disubstituted 1,2,4-triazoles.

open access: yesChemical and Pharmaceutical Bulletin, 1975
Tautomerism of ten 3, 5-disubstituted 1, 2, 4-triazoles, which can exist in three tautomeric forms, has been studied. The nuclear magnetic resonance (NMR) and ultraviolet (UV) spectra of these 1, 2, 4-triazoles were compared with those of the N-methyl derivatives, which are the model compounds of the three kinds of tautomeric forms.
