Descrição: The condensation of amidrazonium iodides with ..beta..-dicarbonyl compounds leads to salts which exist in solutions as tautomeric mixtures of the linear and cyclic forms. The position of the equilibrium depends largely on structural factors. Thermolysis of the salts is accompanied by elimination of the carbonyl compound and the formation of the corresponding 1,2,4-triazolium iodide. Alkaline treatment of the condensation products gives the free bases, which are tautomeric mixtures of the hydrazone and enehydrazine forms in solutions. The thermodynamic parameters ..delta..H/sup 0/ and ..delta..S/sup 0/ of the equilibrium were determined.
