The synthesis of new unsymmetrical and symmetrical macrocycles based on 2, 2′- bipyridine units bearing two or four phenyl groups at the 6 and 6′ positions was achieved by an oxidative coupling reaction using 1, 2-dibromoethane and organolithium derivatives of bipyridine. Among all new compounds prepared, two of them were structurally analysed in the solid state by X-ray diffraction.
