CuO-Catalyzed oxidation of aryl acetates with aqueous tert-butyl hydroperoxide for the synthesis of α-ketoesters was written by Jiang, Jin. And the article was included in Journal of Chemical Research in 2019.Application of 19432-68-9 This article mentions the following:
A practical method to access α-ketoesters ArC(O)C(O)OR [Ar = Ph, 4-BrC6H4, 2-thienyl, etc.; R = Me, iPr, Bn, etc.] via CuO catalyzed oxidation of aryl acetates using aqueous tert-Bu hydroperoxide was developed. No addnl. solvents were required in this method and it was found the peroxide side products in the reaction could be decomposed to products by using pyridine. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9Application of 19432-68-9).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application of 19432-68-9
