Selective oxidation of sulfides to sulfoxides by a vanadium-based catalyst using 30% hydrogen peroxide
The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...

متن کاملOxidation of Sulfides to Sulfoxides by NaBrO3-NH4Cl in Aqueous Acetonitrile
NaBrO3 combined with NH4Cl is found to be an efficient reagent for the transformation of sulfides into sulfoxides in aqueous and under mild conditions.
متن کاملEffective oxidation of sulfides to sulfoxides with hydrogen peroxide under transition-metal-free conditions.
A "green" highly selective oxidation of organic sulfides to the corresponding sulfoxides was developed using hydrogen peroxide and glacial acetic acid under transition metal-free and mild conditions. The oxidation procedure is very simple and the products are easily isolated in excellent yields (90-99%).
متن کاملNanosized mesoporous composite PW12-APTES@KIT-6: An efficient heterogeneous catalyst for selective oxidation of sulfides to sulfoxides and sulfones
Surface of mesostructured silica, KIT-6, was modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H3PW12O40 (PW12). This modified-nanosized mesoporous silica (PW12-APTES@ KIT-6) was characterized by FTIR, XRD, BET and TEM. The oxidation of sulfides occurs effectively and selectively with H2O2 as the oxidant...
