Solid superacids catalyzed organic synthesis. 3. Nafion-H catalyzed condensation of acetophenone derivatives. A preparative route to 1,3,5-triarylbenzenes. was written by Yamato, Takehiko;Hideshima, Chieko;Tashiro, Masashi;Prakash, G. K. Surya;Olah, George A.. And the article was included in Catalysis Letters in 1990.Synthetic Route of C24H15Br3 This article mentions the following:
Nafion-H, a perfluorinated resin sulfonic acid, catalyzes condensation of acetophenones I (R = H, R1 = H, alkyl, MeO, Br, Cl; R = Br, R1 = H) to provide 1,3,5-triarylbenzenes under relatively mild conditions. Reactions are clean and water formed as byproduct does not deactivate the catalyst. However, ortho-substituted acetophenones and 2-acetylthiophene gave no condensation product. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Synthetic Route of C24H15Br3).
3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. 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.Synthetic Route of C24H15Br3
