Herein, a regioselective, late-stage two-step arene halogenation method is reported. We propose how unusual Ni(I)/(III) catalysis is enabled by a combination of aryl thianthrenium and Ni redox properties that is hitherto unachieved with other (pseudo)halides. The catalyst is accessed in situ from inexpensive NiCl·6(HO) and zinc without the need of supporting ligands.
本文报道了一种区域选择性的晚期两步芳基卤化方法。我们提出了芳基噻蒽鎓和 Ni 氧化还原性质的组合如何通过不寻常的 Ni(I)/(III)催化来实现，这是迄今为止其他（假）卤化物所无法实现的。该催化剂可从廉价的 NiCl·6(HO)和锌原位获得，无需使用支持配体。
