Abstract

High-temperature chlorination of an Isolated-Pentagon Rule (IPR) D₂-C₇₆ fullerene followed by high-temperature trifluoromethylation of non-IPR C₇₆ chlorides with CF₃I unexpectedly resulted in a series of non-IPR C₇₆(CF₃)_nF_m compounds. X-ray diffraction study with the use of synchrotron radiation revealed the mixed CF₃/F structures of non-classical, non-IPR C₇₆(CF₃)₁₄, C₇₆(CF₃)₁₄F₂, and C₇₆(CF₃)₁₆F₆.
