Palladium-Catalyzed Intermolecular Arylcarbonylation of Unactivated Alkenes: Incorporation of Bulky Aryl Groups at Room Temperature was written by Li, Xiang;Chen, Pinhong;Liu, Guosheng. And the article was included in Angewandte Chemie, International Edition in 2018.Electric Literature of C9H8S This article mentions the following:
A palladium-catalyzed intermol. arylcarbonylation of unactivated alkenes was developed. Unsym. diaryliodonium salts (DAISs) were used as arylation reagents, the bulky aryl group (ArL) of which was exclusively incorporated into the arylcarbonylated products, which contained the ArL group and a carboxylic ester group at the α- and β-carbon position, resp., of the original terminal C-C double bond. The reaction featured excellent chemo- and regioselectivity, high functional-group tolerance, and very mild reaction conditions. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Electric Literature of C9H8S).
2-Methylbenzo[b]thiophene (cas: 1195-14-8) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Electric Literature of C9H8S
