The transition metal‐free coupling reactions of unactivated diazanaphthalenes were studied using only lithium tetramethylpiperidine (LiTMP) reagent. Symmetrical and nonsymmetrical bis‐diazanaphthalenes were synthesized in moderate to high yield by homo‐ and cross‐coupling of related monomers. In addition, the single‐step synthesis of diquinoxalino [2,3‐a: 2', 3'c] phenazine and 2,2': 3', 2″ ‐ terquinoxaline
