The reaction between perfluoroalkanesulfinate salts (1) [RfSO2MRf=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.
