Аннотация: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.
