Nickel-Catalyzed Ipso/Ortho Difunctionalization of Aryl Bromides with Alkynes and Alkyl Bromides via a Vinyl-to-Aryl 1,4-Hydride Shift was written by He, Yuli;Borjesson, Marino;Song, Huayue;Xue, Yuhang;Zeng, Daning;Martin, Ruben;Zhu, Shaolin. And the article was included in Journal of the American Chemical Society in 2021.Name: 1-Bromo-4-methoxybutane This article mentions the following:
Polysubstituted arenes are ubiquitous structures in a myriad of medicinal agents and complex mols. Herein, a new catalytic blueprint that merges the modularity of nickel catalysis for bond formation with the ability to enable a rather elusive 1,4-hydride shift at arene sp2 C-H sites, thus allowing access to ipso/ortho-difunctionalized arenes from readily available aryl halides under mild conditions and exquisite selectivity profile is reported. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4Name: 1-Bromo-4-methoxybutane).
1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Name: 1-Bromo-4-methoxybutane
