1-Methyl-2,3-dihydro-1,2,4-triazolium iodides can be obtained by reacting methylhydrazones with S-methylthioamide hydriodides, by condensing 2-methylamidrazone hydriodides with aldehydes and ketones, or by reacting methyl iodide with 1-alkylidene(or arylidene)benzamidrazones.In solutions these salts are capable of undergoing tautomerism to 1-alkylidene(or arylidene)-2-methylamidrazone hydriodides.The influence of the structural factors on the position of the tautomeric equilibrium has been studied.The free bases obtained by neutralization of the respective salts by an alkali metal hydroxides are heretofore underscribed 1-alkylidene(or a rylidene)-2-methylhydrazidoimines or 4-triazolines, depending on their structure.Under the action of oxygen, these compounds are readily oxidized to substituted 1-methyl-1,2,4-triazoles with heating.
