説明

Reaction of 2-cyanopyridine with hydrazine was examined using picolinic acid amidrazone (IV) which is an intermediate of this reaction. When the ethanol solution of IV was heated under reflux in nitrogen atmosphere, 3, 6-di (2-pyridyl)-1, 2-dihydro-1, 2, 4, 5-tetrazine (I) and 1, 2-bis (pyridine-2-formimidoyl) hydrazine (III) were obtained. The quantitative study of the reaction suggested that I was not formed via III but they were produced simultaneously. Application of oxygen during refluxing of ethanol solution of IV gave I, III, 3, 6-di (2-pyridyl)-1, 2, 4, 5-tetrazine (V) and 2-pyridinecarboxaldehyde pyridine-2-forminidoylhydrazone (VI).
