The direct and selective phenol coupling reaction that provides biphenols still represents a challenge in organic synthesis. The recently developed electrosynthesis on boron‐doped diamond anodes with fluorinated additives was developed further to allow the application to less‐expensive electrodes and fluorinatedmedia. This advanced protocol allows the highlyselective anodic phenol coupling reaction
