Aryl thioether compound and preparation method thereof
-
Paragraph 0015, (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 Chan-Lam-Type C-S coupling reaction using sodium aryl sulfinates has been developed to provide diaryl thioethers in up to 92% yields in the presence of a copper catalyst and potassium sulfite. Both electron-rich and electron-poor sodium aryl sulfinates and diverse organoboron compounds were tolerated for the synthesis of aryl and heteroaryl thioethers and dithioethers. The mechanistic study suggested that potassium sulfite was involved in the deoxygenation of sulfinate through a radical process.

N-Phenylthiophthalimide reacts with AlCl3 or TiCl4 in arenes to give phenylthiated arenes alone via a phenylsulfenium ion intermediate, modified neglect of diatomic overlap (MNDO) molecular orbital calculations of which revealed that the positive charge preferentially populates the sulfur atom rather than the phenyl group in the phenylsulfenium ion.
