摘要

Abstract Electroreduction of N, N′-dioctyl-4, 4′-bipyridinium bis (triflimide)[C 8 V ²+][Tf 2 N- ] 2 in THF gave a dark blue solution of the corresponding quinoid C 8 V 0, 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,[C 8 V ²+][Tf 2 N-] 2 was recovered and reused for generation of the organic reductant C 8 V 0.
