Abstract

A group of heterocylic compounds of condensed triazole-thiadiazinone derivatives containing fluorine (ma-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-triazole (IIe) with I was difficult due to an intermolecular hydrogen bond of IIe. The structuresof the compounds synthesized were confirmed by LR, MS, H-1 NMR and elemental analyses. Fungicidal and insecticidal activities of these compounds werealso studied.
