Pellizzari Reaction
G. Pellizzari, Gazz. Chim. Ital. 41, II, 20 (1911).
Formation of substituted 1,2,4-triazoles by the condensation of amides and acyl hydrazines. When the acyl groups of the amide and the acylhydrazine are different, interchange of acyl groups may occur with formation of a mixture of triazoles:
