In 2019,New Journal of Chemistry included an article by Wang, Weifan; Luo, Man; Yao, Weiwei; Ma, Mengtao; Pullarkat, Sumod A.; Xu, Li; Leung, Pak-Hing. Recommanded Product: 88-15-3. The article was titled 《Catalyst-free and solvent-free hydroboration of ketones》. The information in the text is summarized as follows:
The hydroboration of a wide range of ketones with pinacolborane can be achieved under catalyst-free and solvent-free conditions to provide the corresponding boronic esters in quant. yields. A large gram-scale hydroboration of acetophenone with HBpin under the same conditions was also performed to afford the alc. product in a high yield thus demonstrating the scalability of the newly developed simple protocol. In the part of experimental materials, we found many familiar compounds, such as 1-Thiophen-2-yl-ethanone(cas: 88-15-3Recommanded Product: 88-15-3)
1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Specialized thiophenes can be synthesized similarly using Lawesson’s reagent as the sulfidizing agent, or via the Gewald reaction, which involves the condensation of two esters in the presence of elemental sulfur. Another method is the Volhard–Erdmann cyclization. Recommanded Product: 88-15-3
