Abstrakt: The anodic polarographic oxidation of aryl- and hetarylformazans in an aprotic medium was investigated. It is shown that this process has two-electron character for arylformazans and one-electron character for hetarylformazans. It was established that the ability to undergo oxidation decreases in the order 2-benzimidazolyl->2-benzothiazolyl->2-pyrimidinyl->2-quinazolinylformazans.
