Base-free oxidation of thiols to disulfides using selenium ionic liquid

Schiff base complex of Cu immobilized on MCM-41 as reusable catalyst for efficient oxidative coupling of thiols and oxidation of sulfides using hydrogen peroxide

“…Likewise, disulfide bond formation is used in sulfenylation of enolates and other anions, industrial applications such as vulcanizing agents [25], bioactive molecules as well as oil sweetening processes and peptide or protein stabilization anions [26], while some disulfides have been found useful as vulcanizing agents for rubber and elastomers imparting them suitable tensile strength [27]. Moreover, they are also relatively more stable in organic reactions such as oxidation, alkylation and acylation compared to the corresponding free thiols, therefore the thiol group can be protected as a disulfide [26].…”

“…Moreover, they are also relatively more stable in organic reactions such as oxidation, alkylation and acylation compared to the corresponding free thiols, therefore the thiol group can be protected as a disulfide [26]. Additionally, in organic synthesis, S-S bonds are used for the synthesis of organo-sulfur compounds via C-S bond formation [28].…”

“…For these reasons, many methods have been developed over the years to find efficient these organic transformations [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. For example, many methods have been reported in the presence of various catalysts and using different oxidant (e.g.…”

Preparation and Characterization of Organically Modified MCM-48 as Heterogonous Catalyst for Oxidation of Sulfides and Thiols

“…For example in chemical processes disulfides can be used to prepare sulfinyl and sulfenyl compounds and in biological systems they control the cellular redox potential and prevent oxidative damage and formation disulfide bond is important in peptides [33][34][35][36]. Furthermore, disulfides are relatively more stable to organic reactions such as oxidation, alkylation and acylation compared to the corresponding free thiols, also the thiol group can conveniently be protected as a disulfide [37]. For the conversion of thiols to disulfides many methods have been developed over the years to find efficient these organic transformations [38][39][40][41][42][43][44].…”

Synthesis of Vinyl Sulfides using Selenium Ionic Liquid

“…Because product isolation or catalyst recycling is very easy in ILs and, in some cases, rate accelerations and/or selectivity improvements are also observed, they are regarded as environmentally friendly green solvents. 4 Due our continuing interest in the synthesis and applications of organochalcogenium chemistry and in new applications for selenium-based ionic liquids, 5 we decide to study the use of [bmim][SeO 2 (OCH 3 )] for the synthesis of vinyl sulfides by hydrothiolation of terminal alkynes.…”
