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 NiCl2·6(H2O) and zinc without the need of supporting ligands.
在此,报道了一种区域选择性的后期两步芳烃卤化方法。我们提出了如何通过芳基噻蒽和 Ni 氧化还原特性的组合实现不寻常的 Ni(I)/(III) 催化,这是迄今为止其他(伪)卤化物无法实现的。该催化剂可从廉价的 NiCl 2 ·6(H 2 O) 和锌原位获得,无需支持配体。
