A new one pot reaction of substituted thiosemicarbazides with 2-bromoacetophenone and carbonyl compounds gave 2-hydrazonothiazoles in good yields. The structures of the isolated compounds were corroborated by NMR, IR, mass spectra and elemental analyses i

The cyclization of 4-phenylthiosemicarbazide with phenacylbromide, carried out in refluxing ethanol, afforded 1,3,4-thiadiazine 1 as the major product. In contrast to a previous report, 2-phenylimino-4-phenyl-2,3-dihydro-1,3-thiazol-3- amine (2) and not 2
