The hydrazinolysis of 2-mercapto[1,2,4]triazolino[3,4-b][1,3,4]triadiazole-5-thione and its S-methyl and disulfonyl derivatives leads to opening of the thiadiazole ring during attack by the nucleophile on the bridge carbon atom. A study of the structures of the reaction products and calculations by the Hückel MO and Pariser-Parr-Pople (PPP) method makes it possible to draw a conclusion regarding the mechanism of the hydrazinolysis.
