A new procedure for the synthesis of aryl methyl sulfides from dimethyl carbonate (DMC) and arylsulfonyl chlorides has been achieved. In this strategy, DMC plays a dual role as both, C1 building block and green solvent. Arylsulfonyl chlorides served as the sulfur precursors, and a variety of aryl methyl sulfides were obtained in moderate to excellent yields with good functional group tolerance. Additionally, alkylsulfonyl chloride and dibenzyl carbonate are proven to be suitable substrates as well.

An efficient route to aryl methyl sulfides through the copper-catalyzed coupling reaction of aryl iodides or bromides with dimethyl disulfide in water is described. Electron-donating and electron-withdrawing functional groups in the substrates were tolerated, and the corresponding products were obtained in moderate to good yields.

A simple iridium catalytic system was developed that allows for a variety of 2-borylthioanisoles to be easily synthesized via ortho-selective C-H borylation of thioanisole derivatives. Once introduced, boryl and methylthio groups were converted by palladium-catalyzed transformations. Density functional theory calculations revealed that weak interactions, such as hydrogen bonding between the C-H bond of the SCH3 group and the oxygen atom of the boryl ligand, control the ortho-selectivity.

We report a tandem reaction to realize reduction of carbon dioxide with thiophenols to generate aryl methyl sulfides under the NaBH4/I2 system with 18-crown-6 as the solvent. Thiophenols bearing electron-donating and electron-withdrawing groups are feasible in this reaction. Controlled experiment results indicate that 18-crown-6 plays a critical role in six-electron reduction of carbon dioxide.

The highly enantioselective enzyme methionine sulfoxide reductase A was combined with an oxaziridine-type oxidant in a biphasic setup for the deracemization of chiral sulfoxides. Remarkably, high ee values were observed with a wide range of substrates, thus providing a practical route for the synthesis of enantiomerically pure sulfoxides.

Rhodium-catalyzed transformation of alkyl aryl sulfides into arylboronic acid pinacol esters via C-S bond cleavage is reported. In combination with transition-metal-catalyzed sulfanyl group-guided regioselective C-H borylation reactions of alkylthioarenes, this method allows the synthesis of a diverse range of multisubstituted arenes.

supporting information, p. 2966 - 2969 (2016/07/06)
A catalytic Miyaura-type ipso-borylation of aryl sulfides with diboron reagents has been achieved, providing arylboronate esters of synthetic use. The key conditions to transform inherently reluctant C-S bonds into C-B bonds include a palladium-NHC (N-heterocyclic carbene) precatalyst, bis(pinacolato)diboron, and lithium hexamethyldisilazide. This protocol is applicable to a reasonable range of aryl alkyl sulfides. Twofold borylation was observed in the reaction of diphenyl sulfide.
