Incorporation of diphenyl disulfide (1) into a pentasil zeolite (Na-ZSM5) results in the formation of the extended radical cation, 1.+, as well as thianthrenlum radical cation (2.+) formed by oxidative cyclization. The stabilization of 1.+ on the internal surfaces of the zeolite is unprecedented because in solution it is converted spontaneously into 2.+. A mechanism for the conversion of 1.+ to 2.+ consistent with processes observed on the internal surfaces of the zeolite is proposed.
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.
