Trimethylsilyl iodide, Me3SiI, reacted in equimolar amount with hexafluoropropene oxide, CF3CFOCF2, in the absence of solvent at elevated temperature, which resulted in the formation of iodopropionyl fluoride, CF3CFICOF, in 43% yield. Iodopropionyl fluoride was converted into its methyl ester, CF3CFICOOCH3, by reacting with excess of methanol. The compounds have been purified by GC and characterized by mass, IR, 1H and 19F NMR spectroscopy.
