by the direct oxidation of aryl Grignard reagents using compressed air in continuous gas‐liquid segmented flow systems is described. The process tolerates a broad range of functional groups, including oxidation‐sensitive functionalities such as alkenes, amines, and thioethers. By integrating a benzyne‐mediated in‐line generation of arylmagnesium intermediates with the aerobic oxidation, a facile three‐step
