Abstract

Direct C2-arylation of NHCs to C2-arylated imidazolium salts (III) is achieved using Ni-catalysis. The dinuclear Ni(i) species I undergoes oxidative addition with ArX to give the Ni(ii) intermediate II. Reductive elimination delivers the arylation product III and regenerates the catalyst I.
