Abstract

4-Alkyl-1-cyanoacetylthiosemicarbazides are cyclised by hydrazine hydrate to 4-alkyl-5-cyanomethyl-1,2,4-triazoline-3-thiones, which at higher temperatures are converted into 4-amino-3,5-di(4-alkyl-3-thioxo-1,2,4-triazolin-5-ylmethyl)triazole derivatives; 4-amino-3,5-di(carbazoylmethyl)-1,2,4-triazole and 4-alkylthiosemicarbazides are also obtained in side-reactions.
