Abstract
Polyfluoromonoiodoalkanes react photochemically with dimethyl sulphide to give as major products the corresponding methyl polyfluoroalkyl sulphides, the corresponding 1H-polyfluoroalkanes, 2,4-dithiapentane and trimethylsulphonium iodide. Thermal reaction of heptafluoro-1-iodopropane with dimethyl sulphide gives a higher yield of 1H-heptafluoropropane, at the expense of methyl heptafluoropropyl sulphide, than in the corresponding photochemical reaction. The products are explained on the basis of a free-radical mechanism.Keywords
