One-pot electrochemical oxidation of alcohols to nitriles was carried out with ammonium acetate as the nitrogen source and 2,2,6,6-tetramethylpiperidinyl-l-oxy (TEMPO) as the catalyst. Cyclic voltammetry investigation showed that an obvious redox reaction between alcohol and TEMPO occurred efficiently in the presence of NH 4 OAc.
