Synthesis, isolation, and X-ray structural characterization of trifluoromethylated C90 fullerenes: C90(30)(CF3)18 and C90(35)(CF3)14


Two CF3 derivatives of C90, C90(30)(CF3)18 and C90(35)(CF3)14, have been isolated via HPLC from the products of a high-temperature trifluoromethylation of a C76–C96 fullerene mixture with CF3I. Their molecular structures were determined by single crystal X-ray crystallography using synchrotron radiation. The addition patterns of the new compounds are discussed in comparison with those of the corresponding chlorinated C90.
