The oxidation of 2-benzimidazolyl- and 2-quinoxalinylhydrazines with selenium dioxide in hydrochloric acid in the presence of cuprous chloride leads to the formation of 2-chloro derivatives of the heterocycles.When the reaction is carried out in ethanol, 2-benzimidazolylhydrazines give symmetrical formazans.In both cases oxidation proceeds through a step involving the formation of hetarenediazonium salts.
