Deoxydichlorination of aldehydes catalyzed by Diphenyl sulfoxide

Chimica Techno Acta, 2021
The diphenyl sulfoxide-catalyzed conversion of aldehydes to 1,1-dichlorides is reported. The reaction proceeds via a sulfurous (IV)-catalysis manifold in which diphenyl sulfoxide turnover is achieved using oxalyl chloride as a consumable reagent.

Sulfoxides. V. The Ionization of Sulfoxides in Sulfuric Acid [PDF]

Bulletin of the Chemical Society of Japan, 1965
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
