Nitrosobenzene reactions
Approximately 95% of nitrobenzene industrially produced is hydrogenated to aniline: C6H5NO2 + 3 H2 → C6H5NH2 + 2 H2O Aniline is a precursor to urethane polymers, rubber chemicals, pesticides, dyes (particularly azo dyes), explosives, and pharmaceuticals. 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
