This invention discloses a method for preparing organothioether compounds, using thiophenol compounds and olefins as raw materials, and reacting them with an alkalizing agent and a catalyst in a solvent under blue light irradiation at room temperature. The method involves using a tert-butanol salt to abstract a hydrogen atom at the S-position of R-thiophenol, generating an R-thiophenol anion. Under light irradiation, the R-thiophenol anion loses electrons to generate an R-thiophenol free radical. The R-thiophenol free radical then passes through Fe... 3+ The method involves catalytic reaction with olefins to yield organosulfur ethers. This well-designed method does not rely on halogens, is relatively reactor- and environmentally friendly, achieves a yield of up to 65%, and is cost-effective. It provides a novel approach for the synthesis of organosulfur ethers and shows promise for industrial applications.
