Nickel-catalyzed intramolecular desymmetrization addition of aryl halides to 1,3-diketones was written by Zhou, Pan;Xu, Tao. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020.Synthetic Route of C7H5Br2F This article mentions the following:
A nickel-catalyzed intramol. addition of aryl halides to 1,3-diketones was first developed. This desymmetrization reaction afforded polycyclic products I [R = Me, i-Bu, Bn, etc.; R1 = H; R2 = H, Cl, OMe, etc.; R3 = H, Me; R4 = H, Me; R1R2 = OCH2O] bearing two tetrasubstituted centers with excellent diastereoselectivities and high yields. Moderate enantioselectivities were achieved in the presence of a chiral ligand. This transformation had great potential for the synthesis of polycyclic compounds including spiro[4,4,3,0] compounds In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Synthetic Route of C7H5Br2F).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) 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 principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Synthetic Route of C7H5Br2F
