“…The radical cation of 1d + • was obtained on treatment of 1d with anhydrous aluminum chloride in CH 2 Cl 2 . Bock and co-workers reported that such treatment of compounds with ionization potentials of approximately 8 eV or less result in their oxidation. The EPR spectrum for 1d + • supports its structure, and the measured g av value is in the range of that reported for other disulfide radical cations .…”

“…Moreover, the radical cation of 1,4-dithiin bisannulated with bicyclo[2.2.2]octene has been shown computationally and by X-ray crystallographic studies to be planar 47j 46c, but it has been suggested 47a,e that these species are 1,2,3-trithiolene radical cations, which are another example of seven-electron π radical cations. …”

“…It is worth noting that stable 1,2-dithiete radical cations were claimed to be generated in solution [124][125][126]. Later work by Passmore and co-workers showed that the EPR parameters of these species were almost identical to those reported for 21a +• implying that, the EPR spectra tentatively assigned to nearly thirty 1,2-dithiete radical cations, were in fact due to 1,2,3-trithiolium radical system 21 +• [123].…”
