Electro-alkynylation: Intramolecular Rearrangement of Trialkynylorganoborates for Chemoselective C(sp2)-C(sp) Bond Formation was written by Music, Arif;Nuber, Constantin M.;Lemke, Yannick;Spiess, Philipp;Didier, Dorian. And the article was included in Organic Letters in 2021.Quality Control of Benzo[b]thiophen-3-ylboronic acid This article mentions the following:
An alternative and complementary transformation for the synthesis of aryl- and heteroaryl-substituted alkynes RCCR1 (R = 4-methylphenyl, 2-(4-fluorophenyl)ethenyl, 1-benzyl-1H-pyrazol-4-yl, etc.; R1 = t-Bu, 2-phenylethyl, 4-methoxyphenyl, etc.) is presented that relies on a chemoselective electrocoupling process. Tetraorganoborate substrates were logically designed and simply accessed by transmetalations using readily or com. available organotrifluoroborate salts RBF3K. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6Quality Control of Benzo[b]thiophen-3-ylboronic acid).
Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Quality Control of Benzo[b]thiophen-3-ylboronic acid
