摘要
The reactions for introducing perfluoroalkyl groups into organic compounds have extensively studied.Most of these perfluoroalkylation reactions are realized by using thecommonly used perfluoroalkylating reagents RI,through addition to various olefins andacetylenes,initiated by means of photolysis,pyrolysis,free radical initiators and differentcatalysts,such as the main group metals,transition metals or their complexes in lower oxida-tion states,NaSOand Ph（OAc）, etc. Recently,perfluoroalkanesulfonyl halide was used to effect perfluoroalkylation,thusthe addition of perfluorosulfonyl chloride with olefin or acetylene was initiated by light orheat,and the perfluoroalkanesulfonyl bromides and iodides can effect the perfluoroalkylationthrough their spontaneous addition to some unsaturated compounds,and in other cases,through actinic,thermal or peroxide initiation.These reactions can be visionalized as
