Reversible Template‐Directed Activation of Equatorial Double Bonds of the Fullerene Framework: Regioselective Direct Synthesis, Crystal Structure, and Aromatic Properties of Th‐C66(COOEt)12

Activation by a template is the key to the very simple, high-yield synthesis of the stable, Th-symmetric C60 hexaadduct 1 (R = COOEt) from fullerene. The data from a crystal structure analysis of 1 shows an enhanced aromaticity in the remaining benzoid π-electron system relative to C60.
