As a case study, we used our platform to perform acid-base titrations alongside cyclic voltammetry to study the electrochemical oxidation of alcohols and aldehydes catalyzed by 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO). TEMPO-catalyzed oxidation proceeds by the catalytic cycle shown in Scheme 1. TEMPO is oxidized at the electrode surface to form TEMPO + , which then reacts irreversibly with the deprotonated form of the alcohol or aldehyde (as a geminal diol), transferring two electrons and a proton from the substrate to TEMPO + , and forming TEMPOH and the respective product molecule. The deprotonation of the substrate molecule prior to the rate limiting irreversible chemical step indicates that the kinetics of the reaction should be affected by the concentration of OH -in solution. TEMPOH may be oxidized at the electrode to TEMPO or engage in comproportionating with TEMPO + to complete the catalytic cycle.
