Chloro‐ and Trifluoromethyl Derivatives of Fullerene C82, C82Cl14 and C82(CF3)14

High‐temperature chlorination of a HPLC fraction containing fullerene C82 resulted in the isolation and X‐ray structure elucidation of the first chloro derivative of IPR C82, C82(3)Cl14. High‐temperature trifluoromethylatiion of a higher fullerene mixture followed by HPLC separation allowed the isolation and structural characterization of a new CF3 derivative, C82(3)(CF3)14. The addition patterns of C82(3)Cl14 and C82(3)(CF3)12–18 are discussed in terms of the formation of stabilizing substructures on a fullerene cage such as isolated C=C bonds and benzenoid rings.
