A DBU-mediated synthesis of 1,3,5-trisubstituted benzenes was developed via the [2 + 4] annulation of in situ activated α,β-unsaturated carboxylic acids and α-cyano-β-methylenones. The dual role of DBU as Bronsted base and nucleophilic Lewis base is the key for the success of the reaction. This study involved multiple reactions and reactants, such as 2-Bromo-5′-phenyl-1,1′:3′,1”-terphenyl (cas: 1890136-54-5Quality Control of 2-Bromo-5′-phenyl-1,1′:3′,1”-terphenyl).
2-Bromo-5′-phenyl-1,1′:3′,1”-terphenyl (cas: 1890136-54-5) 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. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Quality Control of 2-Bromo-5′-phenyl-1,1′:3′,1”-terphenyl
