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

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. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).COA of Formula: C13H11BrS

Hosseini, Seyed Hassan; Tavakolizadeh, Maryam; Zohreh, Nasrin; Soleyman, Rouhollah published an article in 2018, the title of the article was Green route for selective gram-scale oxidation of sulfides using tungstate/triazine-based ionic liquid immobilized on magnetic nanoparticles as a phase-transfer heterogeneous catalyst.Formula: C13H11BrS And the article contains the following content:

Tungstate ions were successfully loaded onto triazine-based ionic liquid-functionalized magnetic nanoparticles through an anion exchange process. The use of triazine core for creating ionic liquid led to the immobilization of high amounts of WO42-. The resulting catalyst showed high activity and selectivity in the oxidation of sulfides to sulfoxides with H2O2 as a green oxidant at room temperature In addition, due to the presence of ammonium groups in the catalyst structure, water dispersibility of the catalyst was increased. More important, the catalyst was magnetically recovered and reused for up to six runs without any marked decrease of activity and selectivity. Finally, easy gram-scale oxidation of methylphenyl sulfide as well as fast separation of catalyst and product makes the protocol economical and industrially applicable. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Formula: C13H11BrS
