Electrolytically generated superoxide reacted with 5-halo-1,2,3-triazines 1 to afford 5-hydroxy-1,2,3-triazines 2. Reaction of 1 with hydroxide anion or potassium superoxide resulted in complicated mixture of products, therefore the reaction was specific for electrogenerated superoxide. The reaction mechanism was investigated with electrochemical methods, and it was revealed that one electron transfer from superoxide to 1 initialized the reaction.
