This paper describes an efficient and regioselective synthetic route leading to new dihalobi- and terpyridines. We developed a strategy based on regioselective sequence of Suzuki– Miyaura cross-coupling reactions between bromopyridyl boronic acids and dihalopyridines and dihalobipyridines. The study of the influence of the nature and the position of the halogen atoms leads to prepare bromoiododerivatives to obtain good selectivities.
