Totally fluorinated sulfones have been known since the pioneering work of Temple in 1968 [1], who prepared the sulfones via the reaction of sulfuryl fluoride or fluorinated sulfonyl fluorides with tetrafluoroethylene (TFE). Since that time, some other perfluorinated sulfones have been reported. Perfluorodimethylsulfone was prepared by direct fluorination [2] and by hydrolysis of bis(trifluoromethyl)difluorosulfoxide [3]. For synthesis of perfluoromethylethylsulfone, the ...
