C₆₀ at 1 mol % loading catalyzed the direct C–H arylation of benzene with aryl iodides in air to yield biaryls. The in situ generation of electron-rich C₆₀(OH)²⁻, from C₆₀ and OH⁻, reduced the aryl iodides to aryl radicals for arylation of benzene. The large surface area and spherical shape of C₆₀ facilitated this process.
