Amangasieva, G. A. published the artcileSynthesis of Amides by Nucleophilic Substitution of Hydrogen in 3-Nitropyridine, Related Products of catalysis-chemistry, the publication is Russian Journal of Organic Chemistry (2018), 54(6), 867-872, database is CAplus.
3-Nitropyridine reacted with nitrogen-centered carboxylic acid amide anions in anhydrous DMSO in the presence of K3Fe(CN)6 via oxidative nucleophilic substitution of hydrogen to give previously unknown N-(5-nitropyridin-2-yl)carboxamides. The reaction of nitrobenzene with urea anion in DMSO enabled one-pot synthesis of bis(4-nitrophenyl)amine.
Russian Journal of Organic Chemistry published new progress about 1821-27-8. 1821-27-8 belongs to catalysis-chemistry, auxiliary class Nitro Compound,Amine,Benzene, name is Bis(4-nitrophenyl)amine, and the molecular formula is C12H9N3O4, Related Products of catalysis-chemistry.
