Oxidative dearomative cross-dehydrogenative coupling of indoles with diverse C-H nucleophiles: efficient approach to 2,2-disubstituted indolin-3-ones was written by Yan, Xue;Tang, Ying-De;Jiang, Cheng-Shi;Liu, Xigong;Zhang, Hua. And the article was included in Molecules in 2020.Product Details of 1190-39-2 This article mentions the following:
The oxidative, dearomative cross-dehydrogenative coupling of indoles with various C-H nucleophiles was developed. This process features a broad substrate scope with respect to both indoles and nucleophiles, affording structurally diverse 2,2-disubstituted indolin-3-ones in high yields (up to 99%). The oxidative dimerization and trimerization of indoles were demonstrated under the same conditions. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Product Details of 1190-39-2).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Product Details of 1190-39-2
