Electrochemical Reductive β‐Arylation and Alkenylation of α‐Branched Acroleins by Primary Amine/Nickel Dual Catalysis

Transformative Chemistry, EarlyView.
A synergistic primary amine/nickel catalysis under electrochemical conditions was developed for cathodic β‐arylation and alkenylation of α‐branched acroleins. The reaction proceeds through β‐enaminyl radicals generated by cathodic reduction of an iminium ion allowing smooth coupling with aryl‐ or alkenyl‐Ni(II) species.
