Solution reactivity of thiyl radicals with molecular oxygen: Unsensitized photooxidation of dimethyldisulfide

Irradiation of dimethyldisulfide in a protic solvent in the presence of molecular oxygen leads to the formation of sulfonic and sulfuric acids as major products. The addition of molecular oxygen on the thiyl radical formed by S-S bond cleavage is postulated.

The method of detecting radicals from low-pressure gas-phase systems by scavenging with dimethyl disulfide (DMD) has been applied to microwave discharges in C//2H//2/He mixtures and to a C//2H//2/O//2 flame. It was accomplished by condensing a supersonic nozzle beam from the reaction system together with a beam of DMD on a liquid-N//2 cooled surface. The scavenging products were measured by GC/MS after warming-up. Radicals measured in the discharge were C//2H, C//4H, C//6H, C//3H//2, C//2 besides H atoms. Preliminary measurements on the flame showed that C//6H//5 (phenyl), CH//2, C//3H//2, besides H and O atoms were prominent radicals at the end of the oxidation zone. The concentration of phenyl is of the same order as that of e. g. naphthalene.
Reaction of methanethiol with species produced in a microwave discharge through water vapor

The products of reaction of methanethiol with species produced by passage of water vapor through a microwave discharge were studied.Mass spectrometric analysis demonstrated the presence of SO2, CH3SSCH3, CH3SSSCH3, CH3SSSSCH3, CH3SSCH2SCH3, CH3SCH2SCH3, and S8.These products are consistent with a mechanism involving abstraction of hydrogen from CH3SH by OH and other radicals as the important primary process.
