The disulfide dication salt, 1,5-dithioniabicyclo[3.3.0]octane bis(trifluoromethanesulfonate) (3), was isolated from the reaction of 1,5-dithiacyclooctane 1-oxide with trifluoromethanesulfonic anhydride. Two-electron oxidation of 1,5-diselenacyclooctane with two equivalents of NOPF6 or NOBF4 gave the first diselenide dication salt, 1,5-diselenoniabicyclo[3.3.0]octane bis(hexafluorophosphate) or bis(tetrafluoroborate) (5). The disulfide and diselenide dication salts (3 and 5) act as an oxidant or as an electrophile depending on the added reagents.
A New Mode of Aromatic Substitution and Redox Reaction of Substituted Benzenes with Disulfide Dication: 1,5-Dithioniabicyclooctane Bis(trifluoromethanesulfonate)

Disulfide dication was found to react with several aromatics to give either the substitution or redox products.The rection mode depends remarkably on the oxidation potential of the aromatics.
