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.
