Perfluoroalkyl derivatives of sulphur. Part XII. The reaction of heptafluoro-1-iodopropane with ethyl methyl sulphide, methyl trifluoromethyl sulphide, and methanethiol

Abstract

The photochemical reaction of heptafluoro-1-iodopropane with ethyl methyl sulphide gives heptafluoro-n-propyl methyl sulphide (7%), ethyl heptafluoro-n-propyl sulphide (21%). 1H-heptafluoropropane (58%), 1,1,1,2,2,3,3-heptafluoropentane (6%), dimethyl sulphide, diethyl sulphide, and minor products. Methyl trifluoromethyl sulphide gives trifluoroiodomethane, heptafluoro-n-propyl methyl sulphide (51%), perfluoro-n-hexane (20%), and 1H-heptafluoropropane (24%); with methanethiol the major products are 1H-heptafluoropropane (85%) and heptafluoro-n-propyl methyl sulphide (14%).
