The direct oxidation of sulfides to sulfones is a wellknown, easy process for many alkyl and aryl substrates, but complications can arise with less reactive, electrondeficient sulfides, particularly perfluoroalkylated ones. Only a few methods for converting perfluoroalkyl sulfides to sulfones have been reported, and they typically require reagents like chromic anhydride or concentrated H2Od trifluoroacetic acidtrifluoroacetic anhydride, l although ...
