Abstract

A method for manufacturing a conjugated aromatic compound comprising reacting an aromatic compound (A) substituted with a halogen as a leaving group with an aromatic compound (A) or an aromatic compound (B) substituted with a halogen as a leaving group and is structurally different from the aromatic compound (A), in the presence of (i) a nickel compound, (ii) a metal reducing agent, (iii) at least one ligand (L1) selected from the group consisting of a 2,2′-bipyridine compound having at least one electron-withdrawing group, and a 1,10-phenanthroline compound having at least one electron-withdrawing group, and (iv) at least one ligand (L2) selected from the group consisting of a 2,2′-bipyridine compound having at least one electron-releasing group, and a 1,10-phenanthroline compound having at least one electron-releasing group.
