review concerns the freeradical chemistry of perfluoroalkyl iodides (RFI) in the synthesis of organic substances of a large variety of structures. Radical chain reactions of RFI are readily initiated by azonitrile initiators and this process generally gives pure products from unsaturated compounds of many types; the process is called iodoperfluoroalkylation. In the synthesis of fluorine containing organic
这项审查涉及全氟烷基碘化物(R F I)在各种结构的有机物质的合成中的自由基化学。R F I的自由基链反应很容易由偶氮腈引发剂引发,该过程通常可从许多类型的不饱和化合物中获得纯净的产物。该过程称为碘全氟烷基化。在合成含氟有机化合物中,很少有方法可以与R F I自由基加成的效率,成本,选择性和多功能性进行比较。第一部分回顾了从R F I生成R F自由基用于合成目的的所有方面并报告R F的相对反应性I和20个典型的烯烃或炔烃。通过实例和实验数据综合表说明了16种不同类别的烯烃和炔烃的实用合成。特别强调了许多这些新的全氟烷基取代的化合物的新颖重要用途。这篇综述的目的是在50年的时间里,将R F I的研究结果集中到一起,作为含氟有机化合物合成的一个切入点。在本文的后续部分中,还将处理其他类别的化合物。

Addition of polyfluoroalkyl halides to alkynes and alkenes bearing a variety of substituents is effected by the catalysis of iron, cobalt and ruthenium carbonyl complexes to give the corresponding adducts in good to excellent yields under mild conditions.
