Résumé

Two CF$_{3}$ derivatives of C$_{90}$, C$_{90}$(30)(CF$_{3}$)$_{18}$ and C$_{90}$(35)(CF$_{3}$)$_{14}$, have been isolated via HPLC from the products of a high-temperature trifluoromethylation of a C$_{76}$-C$_{96}$ fullerene mixture with CF$_{3}$I. 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 C$_{90}$.

Keywords: fullerenes, trifluoromethylation, HPLC
Mots-clés : C$_{90}$, structure elucidation.
