  Synthèse de diènes téléchéliques à partir d' α,ω-diiodo-alcanes fluorés Partie II: Divinyls et diallyls présentant des motifs constitutifs tétrafluoroéthylène, fluorure de vinylidène et hexafluoropropène

  摘要：

  Synthesis of new fluorinated non-conjugated dienes containing tetrafluoroethylene, vinylidene fluoride (VDF) and/or hexafluoropropene from alpha,omega-diiodofluorinated cotelomers was carried out by two methods in two steps. Divinyl monomers were obtained by alpha,omega-bis ethylenation of these cotelomers followed by a bis-dehydroiodination in medium yields which were lower when the cotelomers contained the VDF base unit. Diallylic olefins were produced by addition of these alpha,omega-diiodofluoroalkanes to allyl acetate followed by a 'deiodoacetatization' in high yields. Each telechelic diene was carefully characterized by H-1 and F-19 NMR.

  Linear diiodoperfluoroalkanes are easily synthesized by thermal telomerization of tetrafluoroethylene with iodine. When hexafluoropropene reacts with I(C2F4)nI n=2,3,4 as telogen, new diiodocompounds of formula I(C3F6)m(C2F4)n(C3F6)pI n=2,3,4 m=0,1,2 p=1,2 are obtained. In both cases there are high yields, based both on iodine and on olefin.

  线性二碘全氟烷很容易通过四氟乙烯与碘的热端聚反应合成。当六氟丙烯与I（C 2 F 4）n I n = 2,3,4作为调解剂反应时，新的式I（C 3 F 6）m（C 2 F 4）n（C 3 F 6）p I的二碘代化合物获得n = 2,3,4 m = 0,1,2 p = 1,2。在两种情况下，基于碘和基于烯烃的产率都很高。

  and also for directing the reaction toward the monoadduct or the diadduct are discussed. Both these telomers were reduced with tributylstannane into HC4F8(C3F6)xH (with x=1 or 2) and H–C3F6–C4F8–C3F6–H, the and spectra of which confirmed the structure of each derivative.

  描述了六氟丙烯（HFP）与α，ω-二碘全氟烷烃的热本体端聚反应产生的高度氟化的端粒的合成。涉及1,2-二碘四氟乙烷的反应不成功，因为该二碘化物在190°C时会热分解。考虑到关键参数，例如初始[IC 4 F 8 I] 0 / [HFP] 0摩尔比，反应温度和时间，对涉及1,4-二碘全氟丁烷的端粒化反应进行了优化。IC 4 F 8最高转换的条件讨论了I以及还将反应导向单加合物或二加合物的方法。这两种端粒均被三丁基锡烷还原为HC 4 F 8（C 3 F 6）x H（x = 1或2）和H–C 3 F 6 –C 4 F 8 –C 3 F 6 –H，和其光谱证实了每种衍生物的结构。

  Telomers of perfluoropropylene with alpha,omega-diiodoperfluoroalkanes were converted to branched-chain difunctional condensation monomers. The reaction of ethylene with the telomers gave alpha,omega-bis(iodoethyl)perfluoroalkanes, which were converted to the corresponding diols by reaction with fuming sulfuric acid. The reaction of the branched-chain alpha,omega-bis(iodoethyl)perfluoroalkane a with sodium azide gave the corresponding alpha,omega-bis(azidoethyl)perfluoroalkanes. Hydrogenation of the alpha,omega-bis(azidoethyl)perfluoroalkanes gave diamines. Phosgenation of the amino groups gave diisocyanates.
