Iodoperfluoroalkylnitriles are useful as chain transfer agents in the free radical polymerization of vinyl monomers to form perfluoropolymers. These nitrites provide end groups, which may take part in a cross-linking reaction, if desired, and also have a relatively low toxicity. The resulting perfluoropolymers are useful as molding resins and elastomers, particularly for parts where good chemical resistance and/or high temperature resistance are desirable.

converted into various α-iodo-perfluorocarboxylic acid derivatives or telomerized with tetrafluoroethylene to I(CF2CF2)nOSO2Cl. Ring-opening reaction of perfluoroalkoxypentafluorocyclopropane with iodine at 240 °C produced ICF2CF2COF, which was quenched by alcohol, water, or NH3 to give β-iodo-α,α,β,β-tetrafluorocarboxylic acid derivatives. These functional fluorinated iodides can be used as building blocks
全氟烯烃与I-Cl和ClSO 3 H在温和的条件下反应,得到R F CFICF 2 OSO 2 Cl,可以很容易地将其转化为各种α-碘-全氟羧酸衍生物,也可以用四氟乙烯将其端粒化为I(CF 2 CF 2)n OSO 2 Cl。全氟烷氧基五氟环丙烷与碘在240°C下的开环反应生成ICF 2 CF 2 COF,将其用酒精,水或NH 3淬灭得到β-碘-α,α,β,β-四氟羧酸衍生物。这些功能性氟化碘化物可以用作制备选择性氟化化合物的结构单元。
