A process is disclosed for making diiodofluorinated compounds of the formula ICF2(A)nI wherein n is an integer of at least 1 and each A is CXYCQZ wherein each X, Y, Q and Z are each independently selected from the group consisting of H, F, Cl, RF and ORF, and RF is a perfluoroalkyl group or perfluorinated polyether group wherein one or more of the fluorines is optionally replaced by a substituent selected from the group consisting of chlorine, bromine, iodine, hydrogen, sulfonyl fluoride, nitrile, ester, acyl chloride and acyl fluoride. The process involves reacting an olefin of the formula CXY = CQZ with CF2I2 at a temperature in the range of from about 120 DEG C to 240 DEG C. Diiodofluorinated compounds of the formula ICF2CH2CHRFI are also disclosed.
