, p. 299 - 302 (1997)
The second-order rate constants for the oxidation of various para-substituted thioanisoles with substituted oxo(salen)manganese(v) complexes have been measured spectrophotometrically in acetonitrile at 25°C. Electron-withdrawing substituents in thioanisol

We have developed an eco-friendly and chemo-selective photocatalytic synthesis of sulfoxides or sulfones via oxidation of sulfides (thioethers) at ambient temperature using air or O2 as the oxidant. An inexpensive thioxanthone was used as the photocatalyst. Our method offers excellent chemical yields and good functional group tolerance. The hydrogen bonding between hexafluoro-2-propanol (HFIP) and sulfoxides may play an important role in minimizing the over-oxidization of sulfoxides.
Switchable Synthesis of Aryl Sulfones and Sulfoxides through Solvent-Promoted Oxidation of Sulfides with O2/Air
Cheng, Zhen,Sun, Pengchao,Tang, Ailing,Jin, Weiwei,Liu, Chenjiang
supporting information, p. 8925 - 8929 (2019/11/14)
A practical and switchable method for the synthesis of aryl sulfones and sulfoxides via sulfide oxidation was developed. The chemoselectivities of products were simply controlled by reaction temperature using O2/air as the terminal oxidant and oxygen source. The broad substrate scope, easy realization of gram-scale production, and the simplification of a sulfide oxidation system render the strategy attractive and valuable.
Selective sulfoxidation with hydrogen peroxide catalysed by a titanium catalyst
Postigo, Lorena,Ventura, Maria,Cuenca, Toms,Jimnez, Gerardo,Royo, Beatriz
, p. 320 - 324 (2015/02/02)
A moisture-tolerant cyclopentadienyl-silsesquioxane titanium complex efficiently catalyses the selective oxidation of various types of sulfides to either sulfoxides (TOFs up to 32 530 h-1) or sulfones with H2O2 (30% in water) under mild conditions.
