    • A method for preparing saturated partially fluorinated alkoxy carboxylic acids or salts thereof by treating a compound: (II), where Rf represents a fluorinated, linear or branched alkyl residue interruptible by one or more oxygen atoms, n is 0 or 1, with a Z-anion in a reaction medium comprising water and an organic solvent, where the Z-anion is selected from CN—, SCN— and OCN— or combinations thereof. A method of making partially fluorinated ethers of the general formula (I) wherein Rf is defined as above, n is 0 or 1, and Z is nitrile (—CN), azide (—N3), thiocyanate (—SCN) or cyanate (—OCN) group, said method comprising treating a fluorinated olefin of the general formula (II) wherein the Z-anion is CN—, OCN—, SCN— or N3−. A compound of the general formula (I) as previously described where Z is selected from SCN, OCN and N3.
    • 通过处理化合物(II)制备饱和部分氟化的烷氧基羧酸或其盐的方法,其中Rf表示可被一个或多个氧原子中断的氟化的直链或支链烷基,n为0或1,Z为 阴离子在包含水和有机溶剂的反应介质中,其中Z-阴离子选自CN-,SCN-和OCN-或其组合。 制备通式(I)的部分氟化醚的方法,其中Rf定义如上,n为0或1,Z为腈(-CN),叠氮化物(-N 3),硫氰酸酯(-SCN)或氰酸酯 -OCN)基团,所述方法包括处理通式(II)的氟化烯烃,其中Z-阴离子是CN-,OCN-,SCN-或N 3 - 。 其中Z选自SCN,OCN和N 3,如前所述的通式(I)的化合物。
