Alumina‐mediated C−F activation serves as a unique tool, implementing an algorithm of C−C bond couplings built into a corresponding fluorinated molecule. Instead of a binary code, fluorine atoms are exploited, and their distribution within the fluoroarene was varied in order to attain the most effective sequence of the intramolecular cyclizations. Using diindenochrysene as an example of elusive polycyclic aromatic hydrocarbon (PAH), this work demonstrates the variability inherent to alumina‐mediated HF‐elimination, revealing the two‐step synthesis of diindenochrysene as a climax of the work. The cover artwork was designed by Polina Amsharov. More information can be found in the Communication by K. Amsharov et al. on page 7607.
