Spectres infrarouge et structure de composés cycliques azotés obtenus par l'action des hydrazines sur des derives d'hydrazonates et d'imidates

Hydrazine and monosubstituted derivatives thereof react with N-2 substituted hydrazonates to give pentagonal heterocyclic compounds: N-aminotriazolones from N-2 ethoxycarbonyl hydrazonates, N-aminotriazoles from N-2 acylhydrazonates. The action of hydrazines on N(methoxycarbonylmethyl) benzimidate leads to derivatives of 1,2,4-tetrazine.
