Methylpolyfluoroalkylsulphides, synthesised by two novel routes: (i) photochemical reaction of a polyfluoroiodoalkane with dimethyl sulphide or dimethyl disulphide and (ii) reaction of a polyfluoroiodoalkane with sodium methanethiolate in the presence of dimethyl disulphide, are useful precursors of polyfluoroalkane-sulphonicacids.

the presence of dimethyl disulphide in dimethyl sulphoxide as solvent gives the corresponding methyl polyfluoroalkyl sulphides in high yield (ca. 80%); optimum conditions for the reaction involving heptafluoro-1-iodopropane have been determined. The reaction also works in the absence of the disulphide (yields ca. 70%) and on replacement of the disulphide by dimethyl sulphide. The reactions of hepta
