Nitrobenzene is used as a solvent and as a starting material in the organic synthesis for the preparation of aniline, benzidine, azobenzene, nitrosobenzene, phenylhydroxylamine and acetaminophen. It is also used as a solvent for electrophilic reagents in synthetic chemistry. Further, it is used to prevent the unpleasant odor in shoe, floor and metal polishes. It acts as a precursor to rubber chemicals, azo dyes and pharmaceuticals.
For selective reduction to phenylhydroxylamine with hydrazine hydrate in the presence of rhodium, see: Org. Synth. Coll., 8, 16 (1993).
Electrophilic iodination of the deactivated ring has been effected with N-Iodosuccinimide, A14320, in triflic acid: J. Org. Chem., 58, 3194 (1993).
Commonly used, high dielectric constant solvent, e.g. in Friedel-Crafts reactions. CAUTION! Exothermic reactions can occur with aluminum chloride.
