Abstract
The photochemical reactions of trifluoroiodoethylene and long-chain polyfluoromonoiodoalkanes (C6, C8, and C9) with dimethyl disulphide afford methyl trifluorovinyl sulphide (48%) and methyl polyfluoroalkyl sulphides (73–76%), respectively; oxidation of the latter gives sulphones and thence the corresponding polyfluoroalkanesulphonic acid salts in high yield. Methyl trifluoromethyl sulphide gives trifluoroiodomethane in a photochemical reaction with iodomethane.Keywords
