The electrochemical oxidation of 2-aminobenzimidazole (2-ABT) has been studied in aqueous solution in a wide pH range of 3.0 to 10.8 using a pyrolytic graphite electrode.The initial step in the oxidation at physiological pH involves a 1e, 1H+ reaction leading to the formation of a free radical species, which rapidly dimerizes to give hydrazo intermediate.Further oxidation of hydrazo species in a 2e, 2H+ reaction leads to the formation of azobenzimidazole.Alternatively, the 1e, 1H+ oxidation of protonated 2-ABT gives a cation free radical, which on loss of proton followed by disproportionation gives s-tetrazine derivative of 2-ABT.Both the products have been isolated and characterized. keywords: oxidation / 2-aminobenzimidazole / electrochemistry
