Visible light-driven cross-coupling reactions of alkyl halides with phenylacetylene derivatives for C(sp3)-C(sp) bond formation catalyzed by a B12 complex was written by Chen, Li;Kametani, Yohei;Imamura, Kenji;Abe, Tsukasa;Shiota, Yoshihito;Yoshizawa, Kazunari;Hisaeda, Yoshio;Shimakoshi, Hisashi. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2019.Name: 1-(2-Bromoethyl)-4-methoxybenzene This article mentions the following:
Visible light-driven cross-coupling reactions of alkyl halides with phenylacetylene and its derivatives catalyzed by the cobalamin derivative (B12) with the [Ir(dtbbpy)(ppy)2]PF6 photocatalyst at room temperature are reported. The robust B12 catalyst and Ir photocatalyst provided high turnover numbers of over 33,000 for the reactions. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0Name: 1-(2-Bromoethyl)-4-methoxybenzene).
1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Name: 1-(2-Bromoethyl)-4-methoxybenzene
