The mechanism of these novel reactions has been probed using a combination of experimental and computational methods. The reaction of nitrosobenzene (NB) with an excess of phenyl acetylene (PA) is …
WebbAbstract: The tandem reaction of photoinduced double hydrogen-atom transfer and deoxygenative transborylation for chemo- and site-selective reduction of nitroarenes into aryl amines under catalyst-free, room temperature conditions was disclosed in excellent yields. In this reaction, isopropanol (i PrOH) was used as hydrogen donor and … Webb25 maj 2024 · Among them, nitrobenzene hydrogenation to aniline is one of the most important reaction, since the latter is used as an intermediate in many fields of application, for instance, in the production of isocyanates, rubber processing chemicals, dyes and pigments, agricultural chemicals and pharmaceuticals [ 1 ].
Webb7 mars 2024 · In summary, we have demonstrated that a nitroso compound can be used as an alternative to a dialkyl azodicarboxylate reagent in the Mitsunobu esterification … WebbThe monomer undergoes Diels-Alder reactions with dienes. Most characteristically nitrosobenzene condenses with "active" methylene and amine groups, e.g. of malonic esters. Condensation with anilines affords azobenzene derivatives (Mills reaction) and condensation with benzylcyanide PhCH 2 CN the imine PhC(CN)=NPh (The Ehrlich …
Webb9 juli 2024 · When necessary, NfsA was added to a syringe containing nitrosobenzene, and ascorbate was added to a syringe containing NADPH. Oxygen consumption during the reactions of TNT, tetryl and naphthoquinones with ascorbate was monitored using a Digital Model 10 Clark electrode (Rank Brothers Ltd., Bottisham, UK).
