On Alkylation and Acylation of 5-Hydrazino-1,2,3,4-thiatriazole Derivatives5-Hydrazino-1,2,3,4-thiatriazole reacts with oxo carboxylic acids to give highly unstable 5-carboxyalkylidene-hydrazino-1,2,3,4-thiatriazoles (2). The more stable 5-alkylidenehydrazino-1,2,3,4-thiatriazoles (3) may be alkylated; the thiatriazole system is retained. On action of activated nitriles or isocyanates 1,2,4-thiadiazole (6) or 1,2,4-thiadiazoline derivatives (7) are formed with nitrogen evolution. At temperatures above 40°C, the described thiatriazoles decomposed to give undefinable components.
