Facilitating chemistry: Key to the success of Pd‐catalyzed α‐arylation of oxindoles in continuous flow involved a biphasic system, a precatalyst, and a packed‐bed microreactor. Furthermore, this reaction was integrated into a two‐step continuous‐flow sequence for rapid, modular, and efficient syntheses of 3,3‐disubstituted oxindoles.
