The invention discloses a 4,4'-diphenyl ether dicarboxylic acid synthesis method, which comprises: S1, carrying out a dehydration reaction on p-hydroxybenzoate, an alkali and a solvent at a temperature of 110-120 DEG C for 2-4 h under a protection gas to obtain a mixed solution; S2, adding a catalyst and p-halo benzoate into the mixed solution obtained in the step S1, carrying out a heating coupling reaction at a reaction temperature of 145-195 DEG C, adding a solvent after the reaction is finished, and performing extraction, liquid separation and crystallization to obtain a solid 4,4'-diphenyl ether dicarboxylic acid diester; and S3, carrying out heating hydrolyzing on the 4,4'-diphenyl ether dicarboxylic acid diester obtained in the step S2 in an aqueous alkali solution and a solvent, adding an acid to adjust the pH value to be acidic, and carrying out crystallization and filtration to obtain the 4,4'-diphenyl ether dicarboxylic acid. The method is simple in process operation, low inequipment requirement, high in product purity, less in three wastes generated in the production process, environment-friendly and high in industrial feasibility, and the total yield of the two-step reaction can reach more than 80%.

Visible-light induced oxidative Csp3-H activation of methyl aromatics to methyl esters

Direct functionalization of readily available hydrocarbons under mild conditions fulfills the requirements of green and sustainable chemistry. In this work, a mild and green catalytic oxidative Csp3-H activation of methyl aromatics using O2via photocatalysis has been achieved. A lot of methyl aromatics can be tolerated, providing a green route for aromatic methyl carboxylates. In addition, this protocol can be performed on a gram scale.
