5-Anilino-l,2,3,4-thiatriazole

The study of the complexes of 5-anilino-l,2,3,4-thiatriazolate with transition metals was preliminary reported by Vohs and co-workers <2004MI1>. 

The procedure described for 5-anilino-l,2,3,4-thiatriazole is typical. To a stirred and cooled mixture of 16.7 g. (0.10 mol) of 4-phenylthiosemicarbazide (Eastman-Kodak number 5426) and 76 ml. of 15% hydrochloric acid was added 6.9 g. (0.1 mol) of sodium nitrite in 50 ml. of water. The mode of addition of the sodium nitrite used for the preparation of 5-amino-l,2,3,4-thiatriazole was followed. The white powdery material was recovered by filtration. The yield was 16 g. or 89% of theory. Recrystallization from methanol yields the pure product. 

The diazotization product of 4-phenylthiosemicarbazide is 5-anilino-l,2,3,4-thiatriazole and consists of colorless nee-...
