[a] Reaction condition: 1 M KOH, 100 mM substrates in an H‐cell and electrolysis at 1.478 V vs. RHE. [b] Measured at the initial reaction time of 20 s, as is already pre‐settled by the system. [c] Yields calculated on the basis of HPLC and GC results. [d] We were not able to identify and quantify the products. [e] Ultra‐high current density and fast kinetics are observed, but we could not identify and quantify the products. [f] No reaction. [g] Standard deviations for the yields and FEs are ±2 %.
