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.

1-(5-Aryl-1,3,4-thiadiazol-2-yl)-5-aryltetrazoles (VI) have been obtained by the reaction of 2-aroylamino-5-aryl-1,3,4-thiadiazoles (IV) with phosphorus pentachloride and azidolysis of the resulting imidoyl chlorides.The products obtained on thermolysis o
