A novel two-step onepot synthesis of perfluoroalkyl iodides (α,ω-diiodoperfluoroalkanes) from perfluoroalkyl chlorides (α-chloro-ω-iodoperfluoroalkanes) has been developed by initial conversion to the corresponding sodium perfluoroalkanesulfinates with sodium dithionite and then subsequent oxidation by iodine.

5-dibromo-3-oxaoctafluoropentane (VIII) from the reaction of I or VII with I2 or Br2, respectively, has not been previously recorded in the literature. In the case of iodine this can be regarded as a retro-deiodo-sulfination. However, the reaction of the sulfinate with C12 stops at the sulfonyl chloride stage. Deiodo-sulfination provides a new method for the synthesis of perfluorocarboxylic acids, perfluoroalkyl
在少量对苯二酚的存在下,使3-氧杂八氟戊烷-1,5-二磺酸钾(I),5-碘-3-氧杂八氟戊磺酸亚砜(VII)或7-碘-3-氧杂十二烷基氟庚烷亚磺酸盐(XII)反应)与氢碘酸分别得到相应的全氟羧酸3-氧杂六氟戊二酸(II),5-碘-3-氧杂六氟戊酸(III)或7-碘-3-氧杂十六氟庚酸(XIII)。I或VII与I 2或Br 2分别反应形成的1,5-二碘-3-氧杂八氟戊烷(IV)或1,5-二溴-3-氧杂八氟戊烷(VIII)的形成尚未在以前的文献中记录。文献。在碘的情况下,这可以被认为是后碘脱硫。但是,亚磺酸盐与C1 2的反应在磺酰氯阶段停止。脱碘磺化提供了一种从R F I合成全氟羧酸,全氟烷基溴和全氟磺酸的新方法。
