  Convenient synthesis of thiols and disulfides in the polyfluorinated series incorporating a butylic spacer

  摘要：

  New fluorinated thiols R-F(CH2)(p)SH and disulfides [R-F(CH2)(p)S](2) containing a butylic spacer (p=4) between the perfluorinated part and the thiol (or disulfide) function were easily obtained in good yields with a purity higher than 98%. This allows us to obtain homologues (p>4) for their use as synthetic intermediates or as constituents for molecular organized systems. (C) 2000 Elsevier Science Ltd. All rights reserved.

• Electrochemical fluorination of 4-(perfluoro-n-butyl)-n-butanoyl chloride

  Electrochemical fluorination of 4-(perfluoro-n-butyl)-n-butanoyl chloride produces perfluorooctanoyl fluoride in higher yields than those obtained from n-octanoyl chloride, which is the usual starting material. In particular, one of the by-products of the industrial process, the cyclic perfluoroether perfluoro-2-propyl-tetrahydropyran, is not formed. Also the other by-products. except fluorocarbon

  4-（全氟-正丁基）-正丁酰氯的化学氟化产生的全氟辛酰氟的产率高于从通常的起始原料正辛酰氯获得的产率。特别地，没有形成工业过程的副产物之一，环状全氟醚全氟-2-丙基-四氢吡喃。还有其他副产品。除了氟碳全氟正庚烷以外，其他产品的产量都较低。讨论了这些结果并提出了一种机制。

  Isocyanates are extremely versatile compounds in organic synthesis, but their synthesis is not easy. One of the most convenient methods uses acids as intermediates. In the F-alkyl series, it is sometimes difficult to obtain them by a general way. We have managed an efficient synthetic route to F-alkyl acids through malonates from 2-F-alkylethyl iodides.
