Abstract

We report efficient and extremely fast procedures for the synthesis of novel 3-aryl imino-6-amino-1,2,4,5 dithiadiazines by oxidative cyclisation of 1-aryl bis thioureas using iodine. The bis thioureas are synthesized by microwave irradiation of thiosemicarbazide and aryl isothiocyanate in microwave under solvent free conditions. The structure of the compounds were confirmed by elemental analysis and spectral analysis. (H1-NMR, IR spectra) Key words:
