Abstract
Condensations of β‐dicarbonyl compounds with thiosemicarbazide and 1‐ and 2‐methylthiosemicarbazide give three types of heterocyclic compounds. Depending upon the reagents and experimental conditions, triazepinones, triazepines, 1,2,4‐triazolines or pyrazoles are formed. Mechanisms explaining these cyclisations are proposed.Keywords
