Paragraph 0012; 0014-0027, (2021/04/17)
The invention provides a method for synthesizing 1- naphthoic acid from naphthalene and carbon dioxide, which uses naphthalene as a raw material and Lewis acid as a catalyst, utilizes carbon dioxide as a resource, and directly performs carboxylation reaction to synthesize 1-naphthoic acid. According to the invention, the use of a heavy metal salt catalyst and an oxidizing agent in the traditional process of synthesizing the 1-naphthoic acid by oxidizing the 1-methylnaphthalene is avoided, the carbon dioxide greenhouse gas is introduced, the carbon dioxide is recycled, and the carbon dioxide is used as a carbon source of carboxyl and is subjected to high-selectivity direct carboxylation reaction with the naphthalene to synthesize the 1-naphthoic acid; the atom utilization rate is 100%; the invention has the advantages of high atom economy, no environmental pollution and industrial application prospect.

The oxidation of aldehydes is an efficient methodology for the synthesis of carboxylic acids. Herein we hope to report a simple, efficient and recyclable protocol for aerobic oxidation of aldehydes to carboxylic acid by using C3N4 supported silver nanoparticles (Ag/C3N4) as a catalyst in aqueous solution under mild conditions. Under standard conditions, the corresponding carboxylic acids can be obtained in good to excellent yields. In addition, Ag/C3N4 is convenient for recovery and could be reused three times with satisfactory yields.
