Herein, the first use of CHCl 3 as a “traceless” reagent to trigger a 1,2‐aryl migration for the synthesis of vinyl ketones has been developed. Its success relies on a continuous‐flow strategy that harnesses the synergistic cathodic reduction of CHCl 3 and anodic oxidation of Cl − and carbon‐centered radicals. This electrochemical method operates under catalyst‐free conditions and employs low‐concentration electrolytes along with low‐cost electrodes, thereby enhancing its practicality and sustainability.
