Abstract The synthesis of four 3, 3, 3-trifluoroprop-1-ene telomers (RF (C 3 H 3 F 3) n I, n= 1, 2, RF= nC 6 F 13-or (CF 3) 2 CF-) and their allyl derivatives RF (C 3 H 3 F 3) n CH 2 CH= CH 2 are presented. The allyl telomers were prepared by a three-step reaction. The first step involved the thermal and peroxide-induced bulk telomerization of 3, 3, 3-trifluoroprop-1-ene (TFP) with heptafluoro-2-iodopropane or tridecafluoro-6-iodohexane leading to ...
