• diarylbromonium species by direct anodic oxidation of 2,2'-dibromo-1,1'-biphenyl. The electrochemical method provides access to a range of symmetrically and non-symmetrically substituted cyclic biaryl λ3-bromanes in moderate yields. Keywords: anodic oxidation; cyclic biaryl λ3-bromane; cyclic voltammetry
