Abstract

Electroreduction of N,N′-dioctyl-4,4′-bipyridinium bis(triflimide) [C8V2+][Tf2N-] 2 in THF gave a dark blue solution of the corresponding quinoid C8V0, which worked as an efficient organic reductant for Pd-catalyzed reductive coupling of aryl bromides to give the corresponding biphenyl derivatives in good yields. After usual workup, [C8V 2+][Tf2N-]2 was recovered and reused for generation of the organic reductant C8V0.
