initiation of the radical chain addition of F-n butyl iodide to alkynols through the cathodic reduction of the halide at a carbon cathode is presented. A simplified analysis, based on cyclic voltammetry affords an estimation of the ratio of the rate constants of the two propagation steps, addition of Rf° to alkynol and iodine atom transfer from the F-alkyl iodide to the resulting vinyl radical, involved in
