Palladium-catalyzed tandem N-H/C-H arylation: regioselective synthesis of N-heterocycle-fused phenanthridines as versatile blue-emitting luminophores was written by Yan, Lipeng;Zhao, Dongbing;Lan, Jingbo;Cheng, Yangyang;Guo, Qiang;Li, Xiaoyu;Wu, Ningjie;You, Jingsong. And the article was included in Organic & Biomolecular Chemistry in 2013.Category: benzothiophene This article mentions the following:
A general and highly regioselective synthetic protocol for structurally diverse N-heteroaryl-fused phenanthridines has been developed. Varieties of fluorescence mols. comprising imidazole-fused, benzoimidazole-fused, indole-fused and pyrrole-fused phenanthridines were obtained by this modular approach, some of which exhibit excellent blue-emitting performance, high quantum yields, long fluorescence lifetimes, interesting electrochem. properties, and thermal stabilities. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Category: benzothiophene).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Category: benzothiophene
