A number of salts of alkylidene(arylidene) derivatives of amidrazones was obtained by the reaction of S-methylthioamidium iodides with hydrazones of monocarbonyl compounds.According to the 1H and 13C NMR data, these compounds in solutions are capable of ring-chain tautomerism of the 1-alkylideneamidrazone-1,2,4-triazoline type.The position of the equilibrium is determined chiefly by steric interactions of the substituents attached to the C-N2 bond.
