The reaction between perfluoroalkanesulfinate salts (1) [R_fSO₂MR_f=a,Cl(CF₂)₄;b,Cl(CF₂)₆;c,Cl(CF₂)₈;d,n-C₆F₁₃;e,n-C₈F₁₇;M-Na;K;Hg(I)] and iodine monochloride in dichloromethane at low temperature(e.g.-30- -50℃) resulted in the formation of the corresponding perfluoroalkane-sulfonyl iodides (2),which were identified by their ¹⁹F NMR spectra.The perfluoroalkanesulfonyl iodides generated in situ reacted smoothly with olefins to forum 1:1 adducts with good yields.Thus,these reactions provide another method for the synthesis of the very unstable perfluoroalkanesulfonyl iodide.
