Organic electronics on demand? The palladium‐catalyzed coupling of aromatic ortho ‐diamines with substituted dichloroquinoxalines furnishes N , N ‐dihydrotetraazaacenes, which were oxidized by MnO 2 into the corresponding tetraazapentacenes (see structures; N blue, Cl green, Si yellow). The modular synthesis of these acenes allows the introduction of any substituent by choice of the proper quinoxaline derivative.
