  Novel and practical preparation of α-fluoro-functionalized esters from fluoroiodoacetates

  摘要：

  The addition reaction of fluoroiodoacetates 2 to various electron-rich alkenes 3 initiated by iron powder in dry THF at 70-80 degrees C gave 1 : 1 adducts 4 in good yields. A variety of functionalities in the alkenes such as trimethylsilyl, alkoxy, acetoxy, hydroxy and ester could be tolerated under the reaction conditions. Reduction of the adducts 4 with Zn-AcOH in ethanol or Zn-NiCl2 . 6H(2)O in moist THF was readily accomplished, and the overall procedure was amenable to a convenient one-flask procedure, Treatment of fluoroiodoacetates 2 with electron-deficient alkenes 7 in the presence of an Fe-CrCl3 . 6H(2)O-bpy bimetal redox system in ethanol at 70-80 degrees C resulted in the formation of iodine-free 1 : 1 adducts 8 in moderate to good yields. It is proposed that the addition reactions of fluoroiodoacetates 2 to electron-rich and electron-deficient alkenes proceeded through a single-electron-transfer mechanism.

  omega-dichloroperfluoroalkanes, the similarly stepwise reactions with an alkene is not clean, both bis-adducts and the corresponding omega-hydrides, RCH(2)CH(2)(CF(2))(n)()H as byproducts are also formed. In the absence of alkenes or alkynes, per- and polyfluoroalkyl chlorides can be converted to their sulfinate salts and sulfonyl chlorides.
