Synthesis of 6-Aroylimino-2-aryl-1,3,4-thiadiazolothiadiazolines

Sridevi, G.,Rao, P. Jayaprasad,Reddy, K. Kondal

, p. 997 - 1000 (2007/10/02)

Reaction of 2-amino-5-aryl-1,3,4-thiadiazoles (V) with aroyl isothiocyanates gives 2-aroylamino-5-aryl-1,3,4-thiadiazoles (VII) and N-aroyl-N'-(5-aryl-1,3,4-thiadiazol-2-yl)thioureas (VIII).Contrary to earlier reports, cyclisation of VIII in the presence of PCl5 in POCl3 yields 6-aroylimino-2-aryl-1,3,4-thiadiazolo-thiadiazolines (X).Cyclisation of VIII in the presence of other oxidising agents also leads to X.
