    • There are provided simple processes for preparing a fluoroamide and a fluoronitrile which assure higher yield, i.e., a process for preparing a fluoroamide represented by the formula (2): CF2═CF—Rf—CONH2, wherein Rf is a perfluoroalkylene group or perfluorooxyalkylene group having 2 to 20 carbon atoms, by allowing a fluoroester represented by the formula (1): CF2═CF—Rf—COOR, wherein Rf is as defined above; R is an alkyl group having 1 to 6 carbon atoms, to react with ammonia or ammonium hydroxide, and a process for preparing a fluoronitrile represented by the formula (3): CF2═CF—Rf—CN, wherein Rf is as defined above, by allowing the fluoroamide obtained by the above-mentioned preparation process to react with a dehydrating agent (c) in a solvent (b) having an ether bond, an ester bond, a ketone group or a cyano group.
    • 提供了制备氟代酰胺和确保更高产率的氟腈的简单方法,即由式(2)表示的氟代酰胺的制备方法:CF 2 = CF-R f -C CONH 2,其中R f是全氟亚烷基或全氟氧化烯基 通过使由式(1)表示的氟代酯:CF 2 = CF-Rf-COOR,其中Rf如上所定义,具有2至20个碳原子; R是具有1至6个碳原子的烷基,与氨或氢氧化铵反应,和由式(3)表示的氟腈的制备方法:CF 2 = CF-Rf-CN,其中Rf如上所定义, 通过使通过上述制备方法得到的氟代酰胺与脱水剂(c)在具有醚键,酯键,酮基或氰基的溶剂(b)中反应。
