Abstract 
         The epoxy moiety in a fullerene mixed peroxide can be opened regioselectively by various
            Lewis acids to form halohydrin fullerene derivatives. The first iodofullerene was
            obtained by treating the fullerene epoxide with triphenylphosphine and iodine. A single-crystal
            structure of the chlorohydrin derivative supports the results.
