A New Mode of Aromatic Substitution and Redox Reaction of Substituted Benzenes with Disulfide Dication: 1,5-Dithioniabicyclo[3.3.0] octane Bis(trifluoromethanesulfonate)
Disulfide dication was found to react with several aromatics to give either the substitution or redox products. The reaction mode depends remarkably on the oxidation potential of the aromatics.
