Abstract
Depending on the pH of the medium, when 2-formylquinoxaline hydrate N,N′-dioxide is subjected to attack by the OH− anion, it undergoes redox transformations to give 2-carboxyquinoxaline 4-oxide or quinoline N,N′-dioxide and the formate ion. In the case of attack by the OH− anion 2-formylquinoxaline diethylacetal N,N′-dioxide undergoes only the first reaction, regardless of the pH.
