“…The search for adaptive energy storage technologies and the necessity to close carbon cycles revived this area of research in the last years. In past years, researchers have followed several approaches to emphasize the popularity of (non-)Kolbe electrolysis and increase the mechanistic understanding [47][48][49][50][51][52][53][54][55][56][57]. There is consensus in the literature that, in the first step of Kolbe electrolysis, carboxyl groups adsorb to the anode and are oxidized there to form radicals [48].…”

Spectroelectrochemistry, especially ATR‐SEIRAS, is an emerging method to identify key descriptors for optimizing reaction systems in organic electrosynthesis. Here, the upgrading of biogenic acids via Kolbe electrolysis and reductive transformations was studied. The findings affirm acid group adsorption on electrodes, consistent with existing literature. The effectiveness of Kolbe reaction in suppressing the parasitic ethanol oxidation reaction was observed, whereas it faces stiff competition from the methanol oxidation reaction. Parallel reduction and reductive amination of levulinic acid were uncovered, both relying on adsorbed organic species rather than molecular H2. Intriguingly, the electrode's polarization influences the bond strength, enabling discrimination between acid and ketone species within levulinic acid.

“…Nitriles comprise a chemical substance family which is of high importance in various areas such as chemical industry (where they are extensively used as precursors for plastics, fibers, etc . 43,44 ), or medicine ( e.g. , as biomarkers of chemotherapy-related kidney damage in cancer patients 45 ).…”
