• Functionalization of saturated fluorocarbons with and without light
  作者：Xudong Chen、David M. Lemal

  日期：2006.9

  Photochemical transformation of saturated fluorocarbons into tetrabutylammonium enolates has been improved, and a method employing ketyls as reductants has been developed that accomplishes the same chemistry without light. Enolates have been isolated as enol methyl ethers, from which they can be efficiently regenerated with tetrabutylammonium iodide. In other cases, enolates have been isolated as the

  饱和碳氟化合物向烯丙基四丁基铵的光化学转化已经得到改善，并且已经开发出使用酮基作为还原剂的方法，该方法无需光照即可完成相同的化学反应。烯醇酸酯已经被分离为烯醇甲基醚，可以用碘化四丁基铵从烯醇甲基醚有效地再生它们。在其他情况下，烯醇盐已被分离为相应的酮或稳定的烯醇。氟碳LUMO能量与其反应性相关，并作为选择酮基的指南。讨论了该化学方法在氟聚合物表面改性中的用途。

• 5-Fluoro-substituted pyrazoles
  作者：M. D. Bargamova、S. M. Motsishkite、I. L. Knunyants

  DOI：10.1007/bf00958848

  日期：1990.11

  A preparative method was developed for the synthesis of 5-fluoro-substituted pyrazoles by the reaction of fluoroolefins with substituted hydrazines in the presence of triethylamine. The fluorine atom at the C5 position of the pyrazoles obtained is readily substituted by O-, N-, and S-nucleophiles with the formation of 5-alkoxy-, amino-, mercapto-substituted fluoroalkylpyrazoles.
