Abstract
Anodic oxidation of ethylenediamines (ethane-1, 2-diamines) was investigated by cyclic voltammetry and controlled potential electrolysis in aqueous carbonate buffer (pH 10) at a glassycarbon electrode. The first wave of the diamines is developed at a lower potential than that of the corresponding β-alkanolamines. Among the oxidative bond cleavages, the relative amount of (α) C-(β) C bond fission is larger than that observed for β-alkanolamines and oxidative deamination is only observed after the (α) C-(β) C bond fission. A scheme for the reaction processes is proposed.
