Recyclable Electron Transfer System: Electroreduction of Viologen in Ionic Liquids and Pd-catalyzed Reductive Coupling of Aryl Halides

Recyclable Electron Transfer System: Electroreduction of Viologen in Ionic Liquids and Pd-catalyzed Reductive Coupling of Aryl Halides

Electroreduction of N,N′-dioctyl-4,4′-bipyridinium (C8V2+) bis(triflimide) was carried out in ionic liquids to give the corresponding quinoid C8V0, which promoted reductive coupling of aryl halides in the presence of a Pd catalyst to give biaryls. C8V2+ and the ionic liquids were used repeatedly....
