perfluoroalkane sulphonic acids RFSO3H (RF CF3, C2F5, C4F9) and fluorosulphuricacid. With di-iodo compoundI(CF2)4I, the mono and the diester can be selectively obtained. The alkaline hydrolysis of these esters produces perfluorinated carboxylic compounds. Polyfluorinated iodide R'FCH2CH2I are also oxidized in similar conditions. The mechanism of the electrolytic reaction is discussed.
全氟化磺酸酯[R ˚F SO 3 R ' ˚F和fluorosulphates FSO 3 R' ˚F,很容易被iodoperfluoroalkanes的阳极氧化得到的R” ˚F我在全氟链烷磺酸类R ˚F SO 3 H(R ˚F CF 3,C 2 ˚F 5,C 4 F 9)和氟代硫酸。使用二碘化合物I(CF 2)4 I,可以选择性地获得单和二酯。这些酯的碱水解产生全氟化的羧酸化合物。多氟碘化物R'F CH 2 CH 2 I在类似条件下也会被氧化。讨论了电解反应的机理。
