Copper-Catalyzed Direct Trifluoro- and Perfluoroalkylselenolations of Boronic Acids with a Shelf-Stable Family of Reagents was written by Glenadel, Quentin;Ghiazza, Clement;Tlili, Anis;Billard, Thierry. And the article was included in Advanced Synthesis & Catalysis in 2017.Formula: C8H7BO2S This article mentions the following:
Herein the copper-catalyzed direct perfluoroalkylselenolation of aryl- and vinylboronic acids is described for the first time. The key to success is the design of new shelf-stable perfluoroalkylselenolating reagents, namely perfluoroalkyl tolueneselenosulfonates. The reaction occurs at room temperature in the presence of com. available catalyst and ligand in catalytic quantities. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6Formula: C8H7BO2S).
Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6) 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 found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.Formula: C8H7BO2S
