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 … Nitrosobenzene undergoes Diels–Alder reactions with dienes. Condensation with anilines affords azobenzene derivatives in a reaction known as the Mills reaction. Reduction of nitrosobenzene produces aniline. Most characteristically, nitrosobenzene condenses with active methylene groups, such as those of malonic … Visa mer Nitrosobenzene is the organic compound with the formula C6H5NO. It is one of the prototypical organic nitroso compounds. Characteristic of its functional group, it is a dark green species that exists in equilibrium with its … Visa mer Nitrosobenzene was first prepared by Adolf von Baeyer by the reaction of diphenylmercury and nitrosyl bromide: (C6H5)2Hg + BrNO → C6H5NO + C6H5HgBr A modern synthesis entails reduction of nitrobenzene to Visa mer Nitrosobenzene and other nitrosoarenes typically participate in a monomer-dimer equilibrium. The dimers are often favored in the solid state, whereas the deeply colored monomers are favored in dilute solution or at higher temperatures. The dimers can be … Visa mer
