Abstract

Abstract Effective devotion: An efficient cobalt-catalyzed method devoted to the formation of symmetrical biaryls is described avoiding the preparation of organometallic reagents. Various aromatic halides functionalized by a variety of reactive group reagents are employed. Preliminary DFT calculations have shown that the involvement of a Co I/Co III couple is realistic at least in the case of 1, 3-diazadienes as ligands (FG= functional group ...
