The article was titled 《4CzIPN-tBu-Catalyzed Proton-Coupled Electron Transfer for Photosynthesis of Phosphorylated N-Heteroaromatics》, and you may find the article in Journal of the American Chemical Society.Quality Control of 3,6-Dibromo-9H-carbazole The information in the text is summarized as follows:
2,4,5,6-Tetrakis(3,6-di-tert-butyl-9H-carbazol-9-yl)isophthalonitrile (4CzIPN-tBu) was developed as a photocatalyst for the phosphorus-radical-initiated cascade cyclization reaction of isocyanides. By using 4CzIPN-tBu as catalyst, we developed a visible-light-induced proton-coupled electron transfer strategy for the generation of phosphorus-centered radicals, via which a wide range of phosphorylated phenanthridines, quinolines, and benzothiazoles were successfully constructed. The experimental process involved the reaction of 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Quality Control of 3,6-Dibromo-9H-carbazole)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent.Quality Control of 3,6-Dibromo-9H-carbazole
