A facile preparation of ICF2CF2I in high yield is carried out using a halogen lamp. In a similar manner, ICF2CF2I reacts with ethylene to give ICH2CH2CF2CF2CH2CH2I.

The synthesis of five fluorinated non-conjugated dienes from commercially available α,ω-diiodoperfluoroalkanes is described.Preparation of the fluorinated divinyl derivatives H2C=CH(CF2)nCH=CH2 (n = 2, 4, 6) (2,2, 2,4 and 2,6) was effected by ethylenation of these diiodinated compounds in various ways followed by dehydroiodination in ethanolic potassium hydroxide.Allyl diolefines, H2C=CHCH2(CF2)nCH2CH=CH2 (4,4 and 4,6) were produced by the α,ω-bis-telomerization of allyl acetate followed by deiodoacetoxylation in the presence of zinc.The diacetate precursors 3,4 and 3,6 of the respective diallyls 4,4 and 4,6 were obtained rather than diacetate 3,2 because of the eventual decomposition of α,ω-diiodoperfluoroethane by β-scission.These five fluorinated non-conjugated dienes have been characterized by 1H, 13C and 19F NMR spectroscopy. - Keywords:Telechelic dienes; Fluorinated vinyl dienes; Fluorinated allyl dienes; α,ω-Diiodoperfluoroalkanes; NMR spectroscopy
