The new α ,α ′‐diimine ligands with benzimidazole moiety were synthesized based on the rearrangement of 3‐aroylquinoxalin‐2(1H )‐ones when exposed to 4,5‐diamino‐2,1,3‐benzoxadiazole, 4,5‐diamino‐2,1,3‐benzothiadiazole and 5,6‐diaminoquinoxaline. Among them, we report the first examples of the new heterocyclic system namely benzo[4′,5′]imidazo[1′,2′:1,2]quinolino[3,4‐b and 4,3‐b ][1,2,5]oxadiazolo[3,4‐f ]quinoxalines, which exhibits an interesting electrochemical behavior. All compounds were fully characterized by IR, ¹H and ¹³C NMR spectroscopies, and mass spectrometry.
