Original fluorinated α,ω-diols containing 3,3,3-trifluoropropene (TFP) units were synthesized. The first step dealt with the radical telomerization of TFP with 1,6-diiodoperfluorohexane. Isolated I(TFP)RF(TFP)I diadduct was subsequently reacted with ethylene, and then a two-step hydrolysis gave rise to α,ω-diols in 25% overall yield. The other strategies dealing with the radical addition of I(TFP)RF(TFP)I
