以Ce^4^+-NaHSO3存在的体系中, 全氟烷基碘与烯烃于50-70℃发生加成反应, 得到相应的加成物, 在Fe^3^+-NaHSO3引发下, 或全氟烷基亚磺酸钠存在下也能引发同样的加成反应. 在全氟烷基亚碘酸钠存在下, 于30℃的反应中没有发现全氟烷基亚碘酸钠的全氟烷基与烯烃的加成物形成.

The sulfinatodeiodination reagent Ce4+-NaHSO3 initiates the addition of perfluoroalkyl iodides to olefins at 50-70癈 to give the corresponding adducts in good yield. Similarly, SO3-?generated from Fe3+-NaHWSO3 system can also initiate the same addition although the reagent was not able to cause sulfinatodeiodination. Furthermore it was shown that in the presence of sodium perfluoroalkanesulfinate the same addition also took place and there was no exchange of the perfluoroalkyl groups between sodium perfluoroalkenesulfinate and perfluoroalkyl iodide.
