A group of heterocylic compounds of condensed triazole-thiadiazinone derivatives containing fluorine (IIIa–h) were obtained in good yields by the reactions of the corresponding 3-aryl-5-mercapto-1, 2, 4-triazole (IIa–d) with N-substituted-N-chloromethyl carbamoyl chloride (I) in the presence of potassium carbonate in N, N-dimethylformamide at room temperature. Cyclization of 3-(2, 3, 5-trifluoro-4-methoxyl) phenyl-5-mercapto-1, 2, 4- ...
