PERFLUORO-ω-IODO-3-OXAALKANESULFONYL FLUORIDES AS INTERMEDIATES FOR SURFACTANTS AND VINYL COMPOUNDS

Fluorosulfonyldifluoroacetyl fluoride (FOCCF2SO2F) quantitatively formed from sulfur trioxide and TFE through tetrafluoroethanesultone, has been converted into the octafluoro-5-iodo-3-oxapentanesulfonyl fluoride (ICF2CF2OCF2CF2SO2F) by the well known reaction involving MF, iodine and TFE in aprotic solvents.The iodo compound allowed us to obtain TFE telomers having both fluorosulfonyl and iodo terminal groups.These telomers were easily converted into the surfactants CF3CF2(CF2CF2)nOCF2F2SO3M by fluorination, and into the vinyl derivatives CF2=CF(CF2CF2)nOCF2CF2SO2F by dehalogenation.The scope of this study was to illustrate new methods for the synthesis of perfluoroalkane and perfluoroalkene sulfonates.
