| Abstract: | Fluorinated derivatives of 4H-1,3-benzothiazin-4-one, 1,2,4]triazolo4,3-a]pyrimidine, 1,2,4]triazolo3,4-b]1,3]benzazoles, and 1,5-dihydro-1,2,4-triazole-5-thione were synthesized by addition of hydrazines and their derivatives to tetrafluorobenzoyl isothiocyanate, followed by cyclization of intermediate thiosemicarbazides. |
