Synthesis of blue-red emissive amido-substituted di(het)aryl and tri(het)aryl amine derivatives via chemoselective N-mono and N,N-diarylation of (het) aryl amino amides using benzyne/arynes was written by Meerakrishna, Ramakrishnan Suseela;Shanmugam, Ponnusamy. And the article was included in New Journal of Chemistry in 2019.Quality Control of 3-Aminobenzofuran-2-carboxamide This article mentions the following:
N-mono- and N,N-chemoselective diarylation of an aryl/hetaryl amino amide reaction using benzyne or arynes, an amide-substituted triaryl amine derivative and diaryl amine derivatives were afforded. The scope and limitation of the present study was studied. The products thus obtained were synthetically transformed to highly functionalized biphenyl bridged heterocycles via Suzuki coupling and condensation with 4,4′-biphenyl dialdehyde. Evaluation of the photophys. properties revealed that the triaryl amine derivatives were blue emissive with high quantum yields, whereas the heterocyclic triaryl amine derivatives were blue-red emissive. 3-(Diphenylamino)benzofuran-2-carboxamide was found to be blue emissive with high quantum yield, whereas the 2-(diphenylamino)nicotinamide was found to be red emissive with low quantum yield. In the experiment, the researchers used many compounds, for example, 3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7Quality Control of 3-Aminobenzofuran-2-carboxamide).
3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antiviral, antimicrobial, antitumor, anti-inflammatory.Quality Control of 3-Aminobenzofuran-2-carboxamide
