3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Reference of 10243-15-9

5,6,7,12-Tetrahydrodibenz[c,f][1,5]azabismocines: Highly reactive and recoverable organobismuth reagents for cross-coupling reactions with aryl bromides was written by Shimada, Shigeru;Yamazaki, Osamu;Tanaka, Toshifumi;Rao, Maddali L. N.;Suzuki, Yohichi;Tanaka, Masato. And the article was included in Angewandte Chemie, International Edition in 2003.Reference of 10243-15-9 This article mentions the following:

5,6,7,12-Tetrahydrodibenz[c,f][1,5]azabismocines couple with electron-deficient, electron neutral, and electron-rich aryl bromides in the absence of addnl. activator by using Pd(PPh3)4 as catalyst. Also, one-pot multicoupling reactions were possible by using a combination of 5,6,7,12-tetrahydrodibenz[c,f][1,5]azabismocines, bromophenylboronic esters, and aryl bromides. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Reference of 10243-15-9).
