DiMenna, William S. et al. published their research in Tetrahedron Letters in 1980 | CAS: 6287-82-7

2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.Category: benzothiophene

A convenient preparation of aryl trifluoromethyl ketones was written by DiMenna, William S.. And the article was included in Tetrahedron Letters in 1980.Category: benzothiophene This article mentions the following:

Seven thiophenyl, benzothiophenyl, and benzofuranyl trifluoromethyl ketones were prepared (40-75%) by reaction of CF3CONMe2 with aryllithium reagents, obtained by halogen metal exchange or direct metalation. E.g., 2-(trifluoroacetyl)benzo[b]thiophene was obtained (75%) by sequential treatment of benzo[b]thiophene with BuLi (Et2O, 20°, reflux) and CF3CONMe2 (-85 to -65°, 1 h, 0°), followed by hydrolysis (H2O, 3N HCl). In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Category: benzothiophene).
