Yg. Budnikova et al., DIMER FORMATION IN THE REACTION OF ARYL HALIDES CATALYZED BY NICKEL-COMPLEXES, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(7), 1992, pp. 1299-1300
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 synthesi
zing the catalyst itself by the anodic dissolution of nickel in the pr
esence of 2-bromopyridine in a diaphragmless cell.
