Phosphorus pentachloride-induced transformation of (1,2,3-thiadiazol-5-yl) hydrazones of acetophenone

Reactions of (4-ethoxycarbonyl-1,2,3-thiadiazol-5-yl)hydrazones of acetophenone with PCl5 led to transformation of the 1,2,3-thiadiazole moiety involving four atoms of the side chain to give 6-aryl-5H-[1,2,3] triazolo[5,1-b][1,3,4]thiadiazine-3

Dimroth Rearrangement of 5-Hydrazino-1,2,3-thiadiazoles

The reversible isomerization of 5-hydrazino-1,2,3-thiadiazoles and 1-amino-5-mercapto-1,2,3-triazoles has been established for an ester function at the 4-position (4a 5a).Thus, 4a was isolated by reacting 3a with two equivalents of hydrazine, whereas
