Paragraph 0012, (2021/11/27)
The invention discloses an aryl thioether compound and a synthesis method thereof, wherein an aryl carboxylic acid and a mercaptan (phenol) are used as main raw materials, and a nickel catalyst is prepared. Under the action of the phosphine ligand and the additive, the aryl carboxylic acid and the thiol (phenol) react in an organic solvent, and after the reaction is finished, the corresponding aryl thioether is obtained. The method has the advantages of low cost, high yield, simple and convenient operation, no pollution and the like, and has potential industrial application prospects. The method provides a cheap and green way for preparation of aryl thioether compounds.

A scalable catalytic synthesis method using commodity chemicals for constructing diaryl thioethers directly from sodium arylsulfinates and iodoarenes is reported in this study. In the presence of CuO or other copper salts such as Cu(OAc)2 as well as palladium catalysts, DABCO demonstrated to be essential to promote this transformation. Various iodoarenes and aryl sulfinates were examined and demonstrated the viability of this method. The mechanistic study showed that radical reactions occurred, while DABCO N-oxide radical can be observed by mass spectrometry. A plausible catalytic mechanism involving DABCO is also discussed, suggesting synergistic reduction of sulfinate by Cu(II) and DABCO is the key step of this coupling reaction. (Figure presented.).

A method for Ni-catalyzed controlled decarbonylation of α-ketothioesters is described. Mono- and double-decarbonylations, which gave thioesters and thioethers, respectively, were selectively achieved by changing the ligand. A fundamental study of Ni-catalyzed decarbonylation of α-ketothioesters is presented.
