To a mixture of 18.6 ml (132 mmols) of trifluoroacetic anhydride and 32 ml of trifluoroacetic acid was added dropwise 1.66 ml of a 30% aqueous hydrogen peroxide solution (H2O2, 16.3 mmols and H2O, 71.7 mmols) in an ice bath. After completion of the addition, the mixture was stirred for 3 hours and 0.90 ml (8.13 mmols) of pentafluoroethyl iodide was added thereto, followed by allowing the mixture to react at 0° to 5° C. for 24 hours. The solvent was then distilled off to obtain 3.3 g (85% yield) of di(trifluoroacetoxy)iodopentafluoroethane as a white fluffy crystals.
