Aqueous sodium hypochlorite mediated chemoselective oxidation of chalcogenides to monoxides and dioxides by microwave exposure
Khurana, Jitender,Nand, Bhaskara
, p. 906 - 909 (2010)
A solvent-free, rapid, and highly selective oxidation of sulfides, selenides, and tellurides (chalcogenides) to the corresponding monoxides (sulfoxides, selenoxides, and telluroxides) or the corresponding dioxides (sulfones, selenones, and tellurones) has been developed using aqueous sodium hypochlorite on solid supports by exposure to microwave. Chemoselectivity and quantitative yields have been attained in most cases.

, p. 453 - 463 (2011)
The oxidation of 4-substituted phenyl phenyl sulfides was carried out with several oxo(salen)manganese( V) complexes in MeCN/H2O9 : 1. The kinetic data show that the reaction is first-order each in the oxidant and sulfide. Electron-attracting s

Suzuki-Miyaura coupling of haloarenes is the most widely used protocol for the synthesis of biphenyls. Organosulfur compounds are promising electrophiles since they are abundant in nature and versatile in organic synthesis. We report here the desulfinylative Suzuki-Miyaura coupling of aryl sulfoxides with phenylboronic acids using bench-stable nickel/5-(2,4,6-triisopropylphenyl)imidazolylidene[1,5-a]pyridines as the catalyst. The ligands are readily prepared from common commercial chemicals. The method is applicable to both symmetric and unsymmetric aryl sulfoxides, and a range of biphenyls bearing various functional groups were obtained in up to 94% yield. (Figure presented.).

TeO2-H2O2 system was found to be an efficient selective reagent for the oxidation of sulfides to sulfoxides in the presence of other common functional groups.Over-oxidation of sulfoxides to sulfones was not observed.
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.
Room temperature nickel-catalyzed cross-coupling of aryl-boronic acids with thiophenols: Synthesis of diarylsulfides
Bhowmik, Amit,Fernandes, Rodney A.,Yadav, Mahesh
, p. 2447 - 2458 (2020/04/15)
A NiCl2/2,2′-bipyridine-catalyzed cross-coupling of thiophenols with arylboronic acids has been developed for the synthesis of symmetric and unsymmetric diarylsulfides at room temperature and in air. This methodology is reliable and offers a mild and easy to operate process for the synthesis of arylthioethers, which are essential compounds with applications in the pharmaceutical and agricultural industries. This method avoids the use of expensive transition metals, such as Pd, Ir or Rh, sophisticated ligands and elevated temperatures. It also has a wide substrate scope (55 examples) and provides products in good to excellent yields (72-93%).
