合成含氟有机化合物的重要方法之一是通过对烯烃的氟烷基化,这一过程通常经光、热或自由基引发剂的作用实现。最近,一些过渡金属及其络合物已报道能引发全氟烷基碘对烯烃或炔烃的加成,我们也已发现多种金属如铜粉、Raney镍、铁、钯和铂的络合物等均能引发全氟烷基碘的自由基反应。本文将报道一种更为简便有效的烯烃氟烷基化方法,即由锌粉和全氟烷基碘经单电子转移产生自由基对烯烃的加成。 One of the important ways to synthesize fluorine-containing organic compounds is through the fluoroalkylation of olefins, a process usually carried out by the action of light, heat or radical initiators. Recently, some transition metals and their complexes have been reported to initiate the addition of perfluoroalkyl iodides to olefins or alkynes. We have also found the complexation of various metals such as copper powder, Raney nickel, iron, palladium and platinum All can trigger the free radical reaction of perfluoroalkyl iodide. This article reports a simpler and more efficient method for the fluoroalkylation of olefins by the addition of free radicals to olefins via single electron transfer of zinc powder and perfluoroalkyl iodides.
