Herein, we demonstrate the synthesis of azafluoranthene derivatives under mild conditions via [2+2+2] cycloaddition of 1,6-diynes and nitriles catalyzed by CoBr2/dppp, exhibiting good atom economy. This procedure uses an inexpensive ligand and an earth-abundant metal as catalyst to lower the cost of synthesis. Several azafluoranthenes are produced in 28–95% yields using this approach, featuring mild
