| Abstract: | In the electrochemical oxidation of benzylamine on a Pt electrode at 15–35°C and pH 9.2, 5-amino-6-hydroxy-2,4(1H, 3H)-pyrimidinedione (uramil) was found to be utilized as a current mediator. The oxidized forms of uramil, which attack benzylamine to give N-benzylidene, were assumed to be alloxane ketimine and/or a neutral radical of uramil on the basis of the results of coulometric and kinetic experiments. |
