    • A method for producing fluorinated alcohols from fluorinated alkyl halides can produce fluorinated alcohols at high product yield and at high selectivity in a single-step reaction. The method eliminates the need to use heavy metals and other toxic compounds that are difficult to handle or process.Specifically, the method produces a fluorinated alcohol represented by the following general formula (2): Rf(A)OH  (2) wherein Rf represents a perfluoroalkyl group having 1 to 10 carbon atoms; and A represents a straight-chained or branched saturated hydrocarbon group having 3 to 10 carbon atoms. The method is characterized in that it allows a fluorinated alkyl halide represented by the following general formula (1) to react with an alkali metal salt of 4-hydroxybutyrate in a gamma-butyrolactone solvent: Rf(A)X  (1) wherein Rf and A are as defined above; and X represents a halogen atom.
    • 从氟化烷基卤化物制备氟化醇的方法可以以高产率和在一步反应中以高选择性产生氟化醇。 该方法无需使用难处理或加工的重金属和其他有毒化合物。 具体地说,该方法产生由以下通式(2)表示的氟化醇:<?in-line-formula description =“In-line formula”end =“lead”?> Rf(A)OH(2) 在线公式描述=“In-line Formula”end =“tail”?>其中Rf表示具有1-10个碳原子的全氟烷基; A表示碳原子数3〜10的直链状或支链状的饱和烃基。 该方法的特征在于,其允许由以下通式(1)表示的氟化烷基卤在γ-丁内酯溶剂中与4-羟基丁酸的碱金属盐反应:<?在线配方说明=“In 线型公式“end =”lead“?> Rf(A)X(1)<?in-line-formula description =”In-line Formulas“end =”tail“?>其中Rf和A如上所定义; X表示卤素原子。
