The reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced.
This compound can be prepared by the reduction of nitrobenzene with zinc in the presence of NH 4 Cl. [ 1 ] [ 2 ] Alternatively, it can be prepared by transfer hydrogenation of nitrobenzene using hydrazine as an H 2 source over a rhodium catalyst .
The reaction was first used by Antoine Béchamp to reduce nitronaphthalene and nitrobenzene to naphthylamine and aniline, respectively. [3] The Béchamp reduction is broadly applicable to aromatic nitro compounds. [4] [5] Aliphatic nitro compounds are however more difficult to reduce, often remaining as the hydroxylamine. Tertiary aliphatic ...
Nitrobenzene is an aromatic nitro compound and the simplest of the nitrobenzenes, with the chemical formula C 6 H 5 NO 2. It is a water-insoluble pale yellow oil with an almond-like odor. It freezes to give greenish-yellow crystals. It is produced on a large scale from benzene as a precursor to aniline.
The nitration product produced on the largest scale, by far, is nitrobenzene. Many explosives are produced by nitration including trinitrophenol (picric acid), trinitrotoluene (TNT), and trinitroresorcinol (styphnic acid). [3] Another but more specialized method for making aryl–NO 2 group starts from halogenated phenols, is the Zinke nitration.
Nitrobenzenes are a group of nitro compounds consisting of one or more nitro groups as substituents on a benzene core. They have the formula C 6 H 6–n (NO 2) n, where n = 1–6 is the number of nitro groups. Depending on the number of nitro groups, there may be several constitutional isomers possible. Mononitrobenzene; Dinitrobenzene. 1,2 ...
For compounds consisting of one benzene ring with only nitro groups and hydrogen as substituents, see Category:Nitrobenzenes. Subcategories This category has the following 2 subcategories, out of 2 total.
Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline.
