Synthesis of methyl polyfluoroalkyl sulphides and polyfluoroalkane-sulphonic acids
Abstract
Methyl polyfluoroalkyl sulphides, 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-sulphonic acids.
