And the article was included in Chinese Journal of Chemistry in 2022.HPLC of Formula: 615-55-4 This article mentions the following:
Electrochem. nickel-catalyzed syntheses of triphenylenes e.g., I, by a reductive trimerization of ortho-dibromobenzenes e.g.., 5,6-dibromoindane or ortho-bromoarylsulfurofluoridates e.g., 2-bromo-4-fluorophenyl sulfurofluoridate, or by reductive cross-coupling of ortho-dibromobenzenes to 2,2′-diiodobiphenyls, were described. The former provides a practical means for the construction of triphenylene derivatives e.g., ,I in up to 87% isolated yield at room temperature For 1,2-dihalo-3-methylbenzenes and related ortho-trisubstituted substrates, trimerizations proceed with high substrate-controlled regioselectivity for the non-C3h sym. triphenylene isomer. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4HPLC of Formula: 615-55-4).
3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.HPLC of Formula: 615-55-4
