在电化学条件下，金属卤化物MX（X = I，Br）对不同的芳基硼酸进行了有效的区域选择性自卤化反应。进行了克级反应，以评价方案的适用性。循环伏安法实验表明，在标准条件下，卤阴离子先于芳基硼酸底物被氧化。
An efficient and regioselective ipso-halogenation of diverse arylboronic acids with metal halide salts MX (X = I, Br) has been well established under electrochemical conditions. A gram-scale reaction has been performed to evaluate the applicability of the protocol. Cyclic voltammetry experiments indicated that the halide anion was oxidized prior to the arylboronic acid substrate under standard conditions.
