TL;DR: In this article, the tetrakis(pyridine)silver dichromate in benzene was used to convert carbonyl derivatives of phenylhydrazine, 2-nitrophenylhexine, 4-dinitrophenazine, semicarbozone, and hydroxylamine.
26 citations
TL;DR: In this article, the authors used barium permanganate in refluxing acetonitrile to perform sulfide oxidation to their sulfoxides, which was performed with barium-peranganate.
25 citations
TL;DR: Benzylic oximes are oxidized selectively with barium permanganate in refluxing acetonitrile and produce their corresponding carbonyl compounds in good yields as discussed by the authors.

TL;DR: In this article, it was shown that hydrogen peroxide (H 2 O 2 ) in the presence of zirconium tetrachloride is a very efficient reagent for the oxidation of sulfides to sulfoxides and sulfones in methanol at room temperature.

TL;DR: In this article, the mild oxidation of sulfides to sulfoxides with an aqueous solution of H 2 O 2 (35%) catalyzed by in situ generated dodecyl hydrogen sulfate as Bronsted acid surfactant in the absence of any organic co-solvents and undermetal-free conditions is described.
Abstract: The mild oxidation of sulfides to sulfoxides with an aqueous solution of H 2 O 2 (35%) catalyzed by in situ generated dodecyl hydrogen sulfate as Bronsted acid surfactant in the absence of any organic co-solvents and undermetal-free conditions is described. The method shows high chemoselectivity and the process is highly green for solid sulfoxides which crystallize out immediately after their formation from the reaction mixture. Liquid sulfoxides can be isolated under high vacuum by bulb-to-bulb distillation or by extraction with Et 2 O or EtOAc. Yields of the products are excellent.

TL;DR: In this paper, the selective oxidation of sulfides to sulfoxides by hydrogen peroxide under methyltrioxorhenium(VII) catalysis was examined, and a high selectivity of sulfoxide over sulfone was achieved, except in the presence of water.

TL;DR: In this article, various recent advances in the selective oxidation of sulfides to sulfoxides have been discussed, including those aiming to replace m-chloroperbenzoic acid as the classical sulfide oxidant: Oxone®.
Abstract: This review deals with the various recent advances in the selective oxidation of sulfides to sulfoxides. Non-stereoselective, diastereoselective as well as enantioselective methods are covered. A considerable number of new oxidizing agents have been reported in the last ten to twelve years including those aiming to replace m-chloroperbenzoic acid as the classical sulfide oxidant: Oxone®. dimethyldioxirane, among others. Chiral sulfoxides are especially important in modern asymmetric synthesis, their obtention from prochiral sulfides by Davis' oxaziridines and modifications of Sharp-less procedure are discussed, along with other less common methods. The most newly reported microbiological and enzymatic oxidations are also included.
