A nickel-catalyzed oxidative dehydrogenative coupling reaction of alkane with thiol for the construction of C(sp3)-S bond has been established, affording more than 50 alkyl thioethers. Notably, pharmaceutical and agrochemicals, such as Provigil, Chlorbenside and Pyridaben, were readily synthesized by this approach. The sterically hindered ligand BC and disulfide which was formed in situ oxidation of thiol, efficiently avoiding nickel-catalyst poisoning. A set of mechanistic experiments disclose both Ni-catalyzed and Ni-free HAA processes.
Preparation method of alkyl sulfide

Paragraph 0051, (2019/12/02)
The invention relates to a preparation method of alkyl sulfide. The method comprises the following steps: under the protection of nitrogen, sequentially adding transition metal, a nitrogen ligand, a cocatalyst, an oxidant, a solvent, alkane and thiophenol or mercaptan into a reaction tube, carrying out oxidative dehydrogenation coupling reaction at 80-150 DEG C, ending the reaction after 6-48 hours, evaporating the solvent to dryness, and carrying out column chromatography separation to obtain the alkyl sulfide compound. The method is simple in synthesis process, mild in reaction condition, high in yield and easy to industrialize.
Studies on the stereoselective methylation of α-sulfinyl carbanions generated from three isomeric pyridylmethyl π-tolyl sulfoxides and benzyl 2-pyridyl sulfoxide

A high stereoselectivity in the methylation of 2-pyridylmethyl p-totyl sulfoxide (2a) with lithium diisopropylamide and iodomethane was observed at low temperature. The chelation of Li+ by both the nitrogen atom in the pyridine ring and the sulfinyl oxygen atom in 2a promotes the stereoselectivity as compared with isomeric sulfoxides.
