, p. 1412 - 1418 (2013)
Although selective oxidation of sulfides to sulfoxides with molecular oxygen is a difficult reaction due to the overoxidation to sulfone, manganese oxides were found to catalyze the aerobic oxidation of sulfides to sulfoxides in 1,2- dichlorobenzene at 10

A mild, chemoselective and sustainable biocatalysed synthesis of sulfoxides has been developed exploiting CALB and using AcOEt with a dual role of more environmentally friendly reaction solvent and enzyme substrate. A series of sulfoxides, including the drug omeprazole, have been synthesised in high yields and with excellent E-factors.

Fan, Qiangwen,Zhu, Longwei,Li, Xuhuai,Ren, Huijun,Wu, Guorong,Zhu, Haibo,Sun, Wuji
supporting information, p. 7945 - 7949 (2021/11/01)
A facile and efficient visible-light-mediated method for directly converting sulfides into sulfoxides under clean conditions without using any photocatalysts is reported. This method exhibited favourable compatibility with functional groups and afforded a series of sulfoxides with high selectivity and yields. Moreover, in order to shed more light on such a transformation, detailed mechanism studies were carried out both experimentally and theoretically. The readily accessible, low-cost and eco-friendly nature of the developed method will endow it with attractive applications in chemical synthesis.

A safe, practical and eco-friendly method for the switchable synthesis of sulfoxides and sulfones through visible-light-initiated oxygenation of sulfides at ambient temperature under transition-metal-, additives-free and minimal solvent conditions. The synergistic catalytic efforts between CF3SO2Na and 2-butoxyethyl ether represents the key promoting factor for the reaction. This journal is
Flow Electrosynthesis of Sulfoxides, Sulfones, and Sulfoximines without Supporting Electrolytes
Amri, Nasser,Wirth, Thomas
, p. 15961 - 15972 (2021/07/20)
An efficient electrochemical flow process for the selective oxidation of sulfides to sulfoxides and sulfones and of sulfoxides toN-cyanosulfoximines has been developed. In total, 69 examples of sulfoxides, sulfones, andN-cyanosulfoximines have been synthesized in good to excellent yields and with high current efficiencies. The synthesis was assisted and facilitated through a supporting electrolyte-free, fully automated electrochemical protocol that highlights the advantages of flow electrolysis.
Sulfoxide and Sulfone Synthesis via Electrochemical Oxidation of Sulfides
Lee, Sunwoo,Park, Jin Kyu
, p. 13790 - 13799 (2021/10/12)
The oxidation of diaryl sulfides and aryl alkyl sulfides to the corresponding sulfoxides and sulfones under electrochemical conditions is reported. Sulfoxides are selectively obtained in good yield under a constant current of 5 mA for 10 h in DMF, while sulfones are formed as the major product under a constant current of 10 or 20 mA for 10 h in MeOH. The oxygen of both the sulfoxide and sulfone function is derived from water.
