Copper is the most ancient transition metal used for the synthesis of biaryls and it is still employed nowadays. This part will deal with recent developments in aryl-aryl bond formation using copper derivatives as reagents or catalysts.2002, J Hassan, M Se ́vignon, C Gozzi, E Schulz & M Lemaire* (2002) "Aryl−Aryl Bond Formation One Century after the Discovery of the Ullmann Reaction," Chem.
