    摘要: The present invention provides a process for producing a fluoroalkyl iodide represented by the general formula (II): Rf—CH2CH2I  (II) 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.

    摘要: Perdeuterated methacrylates of a high degree of deuteration can be obtained by a process for the preparation of perdeuterated methacrylates from hexadeuteroacetone by conversion into the corresponding cyanohydrin, subsequent elimination of water, hydrolysis of the cyano group and esterification with perdeuterated alkanols, the conversion of hexadeuteroacetone into the cyanohydrin being effected by reaction with trimethylsilyl cyanide to give 1,3-hexadeutero-2-(trimethylsiloxy)-2-cyano-propane and subsequent hydrolytic elimination of the trimethylsilyl group.
