Hosseinpoor, Farideh,Golchoubian, Hamid
, p. 5195 - 5197 (2006)
Sulfides were selectively oxidized to the corresponding sulfoxides in good yields with hydrogen peroxide using a manganese(III) Schiff-base complex as a catalyst in glacial acetic acid as solvent under mild conditions.
New heteropolyacids as catalysts for the selective oxidation of sulfides to sulfoxides with hydrogen peroxide
Romanelli, Gustavo P.,Vázquez, Patricia G.,Tundo, Pietro
, p. 75 - 78 (2005)
Pyridinium salts of Keggin-type molybdovanadophosphates proved to be highly active catalysts for the hydrogen peroxide oxidation of sulfides to the corresponding sulfoxide and sulfone derivatives. High conversion and high selectivity for sulfoxide were observed.
Ammonium bromide as an effective and viable catalyst in the oxidation of sulfides using nitro urea and silica sulfuric acid
Ghorbani-Choghamarani,Zamani
, p. 142 - 148 (2011)
A new catalytic method for the chemoselective oxidation of sulfides to the sulfoxides has been studied. A variety of dialkyl, alkylaryl and diaryl sulfides were subjected to the oxidation reaction by a mixture of nitro urea, derived from urea nitrate, silica sulfuric acid (SiO2-OSO3H) and catalytic amounts of ammonium bromide in CH2Cl2 at room temperature.

In this work, the immobilization of copper(ii) on the surface of 1,8-diaminonaphthalene (DAN)-coated magnetic nanoparticles provides a highly active catalyst for the oxidation reaction of sulfides to sulfoxides and the oxidative coupling of thiols to disulfides using hydrogen peroxide (H2O2). This catalyst was also applied for the one-pot synthesis of symmetrical sulfidesviathe reaction of aryl halides with thiourea as the sulfur source in the presence of NaOH instead of former strongly basic and harsh reaction conditions. Under optimum conditions, the synthesis yields of sulfoxides, symmetrical sulfides, and disulfides were about 99%, 95%, and 96% respectively with highest selectivity. The heterogeneous copper-based catalyst has advantages such as the easy recyclability of the catalyst, the easy separation of the product and the less wastage of products during the separation of the catalyst. This heterogeneous nanocatalyst was characterized by FESEM, FT-IR, VSM, XRD, EDX, ICP and TGA. Furthermore, the recycled catalyst can be reused for several runs and is economically effective.
