Preparation of substituted triphenylenes via nickel-mediated Yamamoto coupling was written by Schroeder, Zachary W.;LeDrew, Joshua;Selmani, Vanessa M.;Maly, Kenneth E.. And the article was included in RSC Advances in 2021.Name: Dimethyl 4,5-dibromophthalate This article mentions the following:
It was demonstrated that the nickel-mediated Yamamoto coupling of o-dibromoarenes is a concise and efficient way to prepare substituted triphenylenes, including electron-deficient systems that are otherwise challenging to prepare The application of this approach to prepare electron deficient discotic mesogens composed of triphenylenes bearing imide and thioimide groups were also demonstrated. In the experiment, the researchers used many compounds, for example, Dimethyl 4,5-dibromophthalate (cas: 859299-66-4Name: Dimethyl 4,5-dibromophthalate).
Dimethyl 4,5-dibromophthalate (cas: 859299-66-4) 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.Name: Dimethyl 4,5-dibromophthalate
