Study on reactions of 2-amino-5-trifluoromethyl-1,3,4-thiadiazole in alkaline medium

It has been found that reactions of 2-amino-5-trifluoromethyl-l,3,4-thiadiazole in alkaline medium result in recyclization product, bis(5-trifluoromethyl-l,3,4-thiadiazol-2-yl)amine, and dimerization product, 2-(2-amino-5-mercapto-6-trifluoro-1,3,4-triaza-2,4-hexadien-1-yl)-5-trifluoromethyl-1,3,4-thiadiazole being formed and by the reaction with allyl bromide corresponding allyl derivatives are synthesized. The structure of synthesized compounds has been examined by gas chromatography-mass spectrometry and 1H NMR spectroscopy.
