Paragraph 0070-0073, (2021/05/01)
The invention relates to the technical field of organic synthetic chemistry, in particular to a method for promoting synthesis of a beta-hydroxyl selenide compound by visible light. The method comprises the following steps: A, sequentially adding a compound 1 and a compound 2 into a reactor; B, stirring the compound 1 and the compound 2 for reaction at a certain temperature under the irradiation of a light source under an open condition; C, after the reaction is finished, evaporating the solvent under reduced pressure to obtain a crude product; and D, carrying out column chromatography purification to obtain the beta-hydroxy selenide compound 3. According to the method, olefin and diselenide are used as raw materials, one of an acetonitrile/water mixed solvent and an acetone/water mixed solvent is used as a solvent, the reaction temperature is room temperature, and the beta-hydroxyl selenide compound is efficiently synthesized under the irradiation of a white fluorescent light source; compared with the traditional synthesis method, the method has the advantages that the reaction conditions are mild and can be smoothly carried out at room temperature; operation is simple, and all operations can be carried out in an open system; and raw materials are easy to obtain, the yield is high, functional group compatibility is good, and the substrate application range is wide.

Using Se powder as the selenating reagent, the copper-catalyzed double C-Se cross-coupling of aryl iodides, epoxides, and elemental selenium has been developed. This strategy provides a straightforward approach to the synthesis of β-hydroxy phenylselenides with excellent regioselectivity of the ring opening reaction. This process proceeds in generally good yields and is compatible with a broad range of functional groups.
