Hypervalent Iodine(III)‐Catalyzed Balz–Schiemann Fluorination under Mild Conditions

Abstract An unprecedented hypervalent iodine(III) catalyzed Balz–Schiemann reaction is described. In the presence of a hypervalent iodine compound, the fluorination reaction proceeds under mild conditions (25–60 °C), and features a wide substrate scope and good functional‐group compatibility.
