And the article was included in Advanced Synthesis & Catalysis in 2022.Quality Control of 3-Ethynylthiophene This article mentions the following:
A regioselective intermol. carbohalogenation of alkynes with alkenyl bromides enabled by dual photoredox and nickel catalysis was described. This dual protocol enabled an atom-economic access to a wide array of brominated 1,3-dienes from simple starting materials. Broad substrate scope and high regioselectivity were observed The synthetic utility was demonstrated and preliminary mechanistic studies were performed to elucidate the reaction pathway. In the experiment, the researchers used many compounds, for example, 3-Ethynylthiophene (cas: 67237-53-0Quality Control of 3-Ethynylthiophene).
3-Ethynylthiophene (cas: 67237-53-0) belongs to benzothiophene derivatives. Benzothiophene is used as starting material for the synthesis of bioactive molecules. The core structure is a part of various pharmaceutical substances and natural products. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Quality Control of 3-Ethynylthiophene
