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.
Reactivity of Diselenide Dication Salt, 1,5-Diselenoniabicyclooctane Bis(hexafluorophosphate) toward Aromatics. A New Mode of Aromatic Substitution and Redox Reaction

A new diselenide dication salt, 1,5-diselenoniabicyclooctane bis(hexafluorophosphate) was reacted with several aromatics to afford either the substitution or redox products.The reaction mode depends on the oxidation potential of aromatics.
