Switching reaction pathways of (benzo[b]thiophen-3-yl)lithium and (benzo[b]furan-3-yl)lithium based on high-resolution residence-time and temperature control in a flow microreactor was written by Asai, Tatsuro;Takata, Atsushi;Ushiogi, Yousuke;Iinuma, Yoshiharu;Nagaki, Aiichiro;Yoshida, Jun-ichi. And the article was included in Chemistry Letters in 2011.Formula: C9H7BrS This article mentions the following:
The synthesis of the target compounds was achieved by reaction-pathway control of (benzo[b]thiophen-3-yl)lithium and (benzo[b]furan-3-yl)lithium in a flow microreactor system. It was possible to switch between a reaction with an electrophile before ring-opening and after ring-opening at will by choosing an appropriate residence-time and temperature In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Formula: C9H7BrS).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) 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 raloxifene, zileuton, and sertaconazole, and also BTCP.Formula: C9H7BrS
