A new, facile, atom-economical and good regioselective method for the synthesis of benzoin bis-ethers has been developed via directly using readily available alkynes and alcohols as raw materials under visible light irradiation. The protocol utilizes commercial Mes-Acr+ClO4- as an organophotoredox catalyst and air (O2) as a green sustainable reagent. A range of benzoin bis-ether derivatives were easily and efficiently obtained in a one-pot procedure at room temperature, and water is the by-product.

Paragraph 0205-0211, (2019/02/10)
The invention relates to a method for visible light driven green synthesis of benzoin bis-ether. The method comprises the steps that an alkyne compound, an alcohol compound and 10-methyl-9-sym-trimethylbenzene based acridine perchlorate perform driving reaction in the atmosphere at room temperature with the visible light with the wavelength of 450-460 nm, a reaction solution is obtained after 3 hours and is spin-dried to obtain concentrate, and the concentrate is subjected to column chromatography on silica gel to obtain the benzoin bis-ether. The method is high in yield, moderate in conditionand small in environmental pollution.
