METHOD FOR PRODUCING PERFLUOROALKYL COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a perfluoroalkyl compound by the catalytic hydrogenation of a 1-perfluoroalkyl-2-iodo compound, by which the objective perfluoroalkyl compound can selectively be produced in a high yield even at a relative low hydrogen pressure. SOLUTION: This method for producing the perfluoroalkyl compound represented by the general formula: Rf(CH2 )2 R (Rf is a 1 to 20C perfluoroalkyl; R is a substituted or unsubstituted alkyl or acetyl) is characterized by catalytically hydrogenating a 1-perfluoroalkyl-2-iodo compound represented by the general formula: RfCH2 CHIR in the presence of a basic substance and a weakly acidic substance or in the presence of the salt of a basic substance with a weakly acidic substance.
