Abstract

In situ FT-IR and cyclic voltammetry were employed to study the oxidation reaction of benzyl alcohol on platinum electrode with 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO) in CH3CN/H2O solution containing NaClO4. Cyclic voltammograms were characterized by a well-defined one electron reversible redox couple. The possible catalytic oxidation mechanism of benzyl alcohol with TEMPO was studied using in situ FT-IR spectroscopy. It suggested that oxoammonium ion was generated by one-electron oxidation of TEMPO at low oxidation potential and benzyl alcohol was mainly oxidized to benzaldehyde instead of benzoic acid.
