Furthermore, cyclic voltammetry (CV) studies clearly indicate the lack of an oxidation event without adding a base (Figure , bottom panel), which could lead to high potential at the electrode and result in anode fouling. On the other hand, CV of carboxylic acid 29 in the presence of base exhibits an oxidation peak around 1.5 V, which is in good agreement with the reported oxidation potential of alkyl carboxylates. This oxidation event could be acting as overcharge protection, thus maintaining the integrity of the electrodes throughout the reaction. Following the acidity study highlighted in Figure , further CV studies were undertaken to provide a more detailed analysis on the impact of AP on this decarboxylative process (Figure ). In order to replicate the reaction process as closely as possible, a graphite electrode was used as working electrode, and potential was swept for 10 cycles between +3 V and different low ends. Three values were chosen for the low end: 0 V (barely reductive), -1.0 V (reductive, but no solvent reduction), and -2.5 V (sufficiently reductive for solvent reduction to occur). Notably, in the +3 -0 V window, the oxidative current intensity dropped considerably after the first cycle, possibly indicating electrode fouling. Lowering the reductive end of the window to -1.0 V attenuated this current drop. Upon reaching -2.5 V, a new reductive event associated with acetone reduction was observed, and the oxidative current intensity was maintained during ten cycles. This result indicates that the reduction of acetone, which consumes protons, is crucial to support smooth decarboxylation over time, thus resupplying carboxylate species for further oxidation. Based on the observation of isopropanol in crude 1 H NMR on preparative scale, this scenario likely explains the role of AP.
