ABSTRACT:
The present invention provides a process for producing a fluoroalkyl iodide represented by the general formula (II):in-line-formulae description="In-line Formulae" end="lead"?Rf-CH2CH2I  (II)in-line-formulae description="In-line Formulae" end="tail"?wherein Rf is a perfluoroalkyl or polyfluoroalkyl group comprising 1 to 20 carbons, the process comprising reacting hydrogen iodide gas with a fluoroalkene in the presence of a catalyst. The present invention also provides a process for producing a fluoroester by reacting the fluoroalkyl iodide with a carboxylate.
