Diisobutylaluminum Hydride Promoted Selectivity-Switchable Synthesis of Benzothiophene Oxides and Benzothiophenes via an Al-Li-Dimetalated Intermediate was written by Uchida, Seiya;Kinoshita, Hidenori;Miura, Katsukiyo. And the article was included in Organic Letters in 2020.Product Details of 6287-82-7 This article mentions the following:
Author developed an efficient and direct method for synthesis of benzothiophene oxides I (R = H, 6-Me, 6-F, etc.) from 1-bromo-2-[2-(trimethylsilyl)ethynyl]benzenes and thionyl chloride as an easily accessible source of the sulfinyl group. Benzothiophenes II (R = H, 6-Me, 6-F, etc.) were also synthesized selectively by simply increasing the amount of thionyl chloride. These methods achieved efficient syntheses of various benzothiophene oxides and benzothiophenes. The further modification of the benzothiophene oxides obtained was also demonstrated. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Product Details of 6287-82-7).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is also used in the manufacturing of dyes such as thioindigo.Product Details of 6287-82-7
