Sulfoxides. V. The Ionization of Sulfoxides in Sulfuric Acid [PDF]
Abstract Contrary to the earlier claim that diphenyl sulfoxide ionizes in nearly 100% sulfuric acid to give a “diphenyl sulfidonium” ion, which can then return to the original sulfoxide when quenched with water, the 18O tracer experiment and a new set of cryoscopic determinations of a few sulfoxides have revealed that the dissociation of

Deoxidation of Fenthion Sulfoxide, Fenthion Oxon Sulfoxide and Fensulfothion in Gas Chromatograph/Mass Spectrometer, and the Prevention of Sulfoxide Deoxidation by Polyethylene Glycol 300 [PDF]
Fenthion, fenthion sulfoxide, fenthion oxon sulfoxide and fensulfothion showed two different mass spectra in GC/MS, depending on their concentrations. The base peaks shifted to lower levels by 1 m/z at lower concentration, and no retention time shifts ...
