Synergy of anodic oxidation and cathodic reduction leads to electrochemical deoxygenative C2 arylation of quinoline N-oxides

The first example of electrochemical deoxygenative C2 arylation of quinoline N-oxides using sulfonyl hydrazines was demonstrated in this work. By employing both anodic oxidation and cathodic reduction, a variety of 2-arylquinolines were synthesized under metal catalyst-, exogenous-oxidant-, and exogenous-reductant-free conditions.
