| Abstract: | Enlarged scope by fluorinated mediators : Oxyl radicals are easily formed on boron‐doped diamond (BDD) electrodes and can be exploited for the ortho‐selective coupling to the corresponding biphenols (see scheme). At partial conversion, a clean transformation is achieved that can be applied to electron‐rich as well as fluorinated phenols.  |
