Synthesis, Structures, and Properties of Cyclopenta‐Fused Anthra[1,2‐ a ]anthracene Derivatives as New Polycyclic Aromatic Compounds

Three new cyclopenta-fused (CP) polycyclic aromatic compounds were synthesized from anthra[1,2-a]anthracenes by direct C─C bond formation in the internal region by Scholl reaction or by benzo fusion at the external corner through Pd-catalyzed cyclization. X-ray analysis and DFT c...
