In this article, we show that tribromide heterogenized on the surface of silica-coated magnetic nanoparticles modified with N2,N4,N6-tris(aminomethyl)-1,3,5-triazine-2,4,6-triamine [Fe3O4@SiO2-tris(triazine-triamine)-Br3] is a novel and efficient reusable nanocatalyst for the oxidation of sulfides to sulfoxides and oxidative coupling of thiols to disulfides using hydrogen peroxide as green oxidant. The structure of the as-fabricated Fe3O4@SiO2-tris(triazine-triamine)-Br3 was characterized by a series of spectroscopic techniques including FT-IR spectroscopy, SEM, TEM, EDX, VSM, XRD and TGA techniques. TEM and SEM anal. confirmed that the typical silica shell thickness was assessed to be around 20 nm. Recycling studies revealed that the Fe3O4@SiO2-tris(triazine-triamine)-Br3 could be easily recovered by a simple magnetic separation and recycled at least 6 times without deterioration in catalytic activity.

And the article contained the following:

A sulfonium ylide participated alkylation and arylation under transition-metal free conditions was described. The disparate reaction pattern allowed the sep. activation of non-ylidic S-alkyl and S-aryl bond. Under acidic conditions, sulfonium ylides served as alkyl cation precursors which facilitated the alkylations. While under alk. conditions, cleavage of non-ylidic S-aryl bond produces O-arylated compounds efficiently. The robustness of the protocols were established by the excellent compatibility of wide variety of substrates including carbohydrates.

On May 4, 2001, Bravo, Anna; Dordi, Barbara; Fontana, Francesca; Minisci, Francesco published an article.Application of 53136-21-3 The title of the article was Oxidation of Organic Sulfides by Br2 and H2O2. Electrophilic and Free-Radical Processes. And the article contained the following:

The bromine-catalyzed oxidation of sulfides with hydrogen peroxide was studied. Diaryl sulfides do not react with hydrogen peroxide and a catalytic amount of bromine; the latter is consumed by electrophilic aromatic substitution and no further reaction occurs. Dibenzyl sulfide reacts with hydrogen peroxide and a catalytic amount of bromide leading mainly to dibenzyl sulfoxide and minor amounts of benzyl bromide, benzenemethanesulfonic acid, benzyl alc. and benzaldehyde. Benzyl bromide and benzenemethanesulfonic acid were obtained in almost quant. yield by using stoichiometric amounts of bromine in the absence of hydrogen peroxide. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Application of 53136-21-3
