Fullerene C₆₀ was reacted with SF₅CF₂CF₂I and SF₅CF₂I in the presence of Cu powder at 140–180 °C resulting in the successful production of the first pentafluorosulfanyl-functionalized fullerenes. In contrast to perfluoroalkyl iodides, which typically form (poly)perfluoroalkylfullerenes upon heating, the SF₅CF₂CF₂I reagent produced three types of products, cycloadducts C₆₀(c-C₂F₄)_n, pentafluorosulfanyl products C₆₀(CF₂CF₂SF₅)_m, and the mixed derivatives C₆₀(C₂F₄)_n(CF₂CF₂SF₅)_m. The optimization of the reaction conditions resulted in improved selectivity for the bis-adduct 1,7-C₆₀(CF₂CF₂SF₅)₂, which was isolated and spectroscopically characterized. In the case of reactions between C₆₀ and SF₅CF₂I, the unexpected formation of a mixture of derivatives with the general formula C₆₀(CF₃)_n(CF₂SF₅)_m was observed.

在铜粉存在下，在140–180°C下，富勒烯C ₆₀与SF ₅ CF ₂ CF ₂ I和SF ₅ CF ₂ I反应，成功生产了第一批五氟硫烷基官能化的富勒烯。与通常在加热时形成（聚）全氟烷基富勒烯的全氟烷基碘化物相反，SF ₅ CF ₂ CF ₂ I试剂产生三种类型的产物，环加合物C ₆₀（c -C ₂ F ₄）_n，五氟硫烷基产物C ₆₀（CF ₂ CF₂ SF ₅）_m和混合衍生物C ₆₀（C ₂ F ₄）_n（CF ₂ CF ₂ SF ₅）_m。反应条件的优化导致对双加合物1,7-C ₆₀（CF ₂ CF ₂ SF ₅）_2的选择性提高，该双加合物已分离并通过光谱表征。在C ₆₀和SF ₅ CF ₂之间发生反应的情况下在图I中，观察到意外地形成了具有通式C ₆₀（CF ₃）_n（CF ₂ SF ₅）_m的衍生物的混合物。
