A simple cobalt complex, such as Co(phen)Cl2, turned out to be a highly efficient and cheap precatalyst for a host of cross-coupling reactions involving aromatic and aliphatic organoaluminum reagents with aryl, heteroaryl and alkyl bromides. New C(sp2)–C(sp2) and C(sp2)–C(sp3) bonds were formed in good to excellent yields and with high chemoselectivity, under mild reaction conditions.
