Sensitized photooxidation of 1,5-dithiacyclooctane (1,5-DTCO) has been investigated in various solvents. At high conversions, a novel C-S bond cleavage occurs. Significant solvent effects are also observed. At high concentration (0.05-0.1 M) in methanol, more than 90% of the corresponding monosulfoxide and a mixture of cis- and trans-bissulfoxides are produced. In aprotic solvents (benzene, chloroform, acetone, and acetonitrile), novel cleavage products (1,2-dithiolane 1-oxide, 1,2-dithiolane 1,1-dioxide, and acrolein) were obtained in addition to the monosulfoxide and bissulfoxides. The cleavage products derive mostly from reaction of the primary monosulfoxide (1,5-DTCO 1-oxide) with singlet oxygen. Unstable compounds oxidized α to the sulfur atom were detected by NMR spectroscopy and shown to be intermediate in the formation of the cleavage products.

The disulphide dication salt, 1,5-dithioniabicyclooctane bis(trifluoromethanesulphonate) (1) was reduced upon treatment with carbanions or alkoxides; it did not deprotonate.
A New Mode of Aromatic Substitution and Redox Reaction of Substituted Benzenes with Disulfide Dication: 1,5-Dithioniabicyclooctane Bis(trifluoromethanesulfonate)

Disulfide dication was found to react with several aromatics to give either the substitution or redox products.The rection mode depends remarkably on the oxidation potential of the aromatics.
A new preparative method, characterization, and reactivity of disulphide dication salts of cyclic bis-sulphides: R2S-SR2· 2CF3SO3-

The reaction of 1,5-dithiacyclo-octane 1-oxide with trifluoromethanesulphonic anhydride affords the corresponding disulphide dication as a stable crystalline salt which serves as an oxidizing agent in the oxidation of 1,2-diphenylhydrazine; the disulphide dication of 1,4-dithiane has also been isolated.
