Abstract

HMO calculations were performed for all possible tautomeric forms of different 1,2,4-triazole derivatives1–4 and their condensed ring analogues5–8. The resonance energies obtained showed this method useful for the differentiation of the tautomeric structure of the planar monocyclic 1,2,4-triazole derivatives but it did not give satisfactory results in case of their non-planar condensed ring analogues.

Zusammenfassung

Die HMO-Methode wurde für alle möglichen tautomeren Formen der 1,2,4-Triazol-Derivate1–4 und deren kondensierte Analogen5–8 verwendet. Die berechneten Resonanzenergien bewiesen, daß dieHückel-Methode gute Resultate für die Unterscheidung verschiedener tautomerer Formen der planaren 1,2,4-Triazol-Derivate, aber nicht für deren nicht-planare kondensierte Analogen ergibt.
