The missing links between the normal, planar polycyclic aromatic hydrocarbons and buckyballs are the bowl‐shaped C 30 H 12 buckybowls 1 , 2 , and 3 . All three were prepared by flash vacuum pyrolysis of suitable aromatic precursors. The best yields are obtained when radical centers are generated at defined positions by the homolysis of CBr and CC bonds to initiate the critical cyclizations.
