Dimer formation in the reaction of aryl halides catalyzed by nickel complexes

Abstract

The synthesis of diaryls catalyzed by electrochemically generated zero-valent nickel with 2,2′-diapyridyl as the ligand was carried out from aryl halides in high yield. Feasibility was demonstrated for synthesizing the catalyst itself by the anodic dissolution of nickel in the presence of 2-bromopyridine in a diaphragmless cell. © 1993 Plenum Publishing Corporation.
