- Radical Ions, 51. Oxidative Rearrangement of Diphenyl Disulfides to Thianthrenes
-
para-Substituted diphenyl disulfides 1 - 5 with low gas phase ionization energies of about 8 eV react with AlCl3 in CH2Cl2 to form radical cations of the corresponding thianthrenes (Table 2, Figure 2).Warming of these solutions produced a second ESR signal which is attributed to a benzodithiete radical cation (Table 2, Figure 3).This is possibly the reactive intermediate in the S8 or S2Cl2 catalyzed Friedel-Crafts chlorination of benzene.
