Cobalt-catalyzed carboxylation of aryl and vinyl chlorides with CO2 was written by Wang, Yanwei;Jiang, Xiaomei;Wang, Baiquan. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020.Synthetic Route of C8H5BrS This article mentions the following:
The transition-metal-catalyzed carboxylation of aryl and vinyl chlorides with CO2 is rarely studied, and has been achieved only with a Ni catalyst or combination of palladium and photoredox. In this work, the cobalt-catalyzed carboxylation of aryl and vinyl chlorides and bromides with CO2 has been developed. These transformations proceed under mild conditions and exhibit a broad substrate scope, affording the corresponding carboxylic acids in good to high yields. In the experiment, the researchers used many compounds, for example, 4-Bromobenzo[b]thiophene (cas: 5118-13-8Synthetic Route of C8H5BrS).
4-Bromobenzo[b]thiophene (cas: 5118-13-8) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. It is also used in the manufacturing of dyes such as thioindigo.Synthetic Route of C8H5BrS
