Isatin 3-thiobenzoylhydrazone undergoes cyclization with the addition of the sulfur atom to the C3 atom and closure of the thiadiazole ring.In contrast, 3-thioaroylhydrazones of 1-acetylisatin undergo cyclization with participation of C2 and close the thiadiazine ring with the formation of derivatives of the new heterocyclic system thiadiazinoindole.
