The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally. The nitro group is also strongly electron-withdrawing. Because of this property, C−H bonds alpha (adjacent) to the nitro group can be acidic. For similar reasons, the presence of nitro groups in aromatic compounds retards ...
Nucleophilic aromatic substitution. A nucleophilic aromatic substitution ( SNAr) is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring. Aromatic rings are usually nucleophilic, but some aromatic compounds do undergo nucleophilic substitution.
RSC ontology ID. RXNO:0000498. The Béchamp reduction (or Béchamp process) is a chemical reaction that converts aromatic nitro compounds to their corresponding anilines using iron as the reductant: [1] 4 C6H5NO2 + 9 Fe + 4 H2O → 4 C6H5NH2 + 3 Fe3O4. This reaction was once a major route to aniline, but catalytic hydrogenation is the preferred ...
Nitration. In organic chemistry, nitration is a general class of chemical processes for the introduction of a nitro group ( −NO2) into an organic compound. The term also is applied incorrectly to the different process of forming nitrate esters ( −ONO2) between alcohols and nitric acid (as occurs in the synthesis of nitroglycerin ).
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. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro compounds.
Structural formula of nitroso group. In organic chemistry, nitroso refers to a functional group in which the nitric oxide (−N=O) group is attached to an organic moiety.As such, various nitroso groups can be categorized as C-nitroso compounds (e.g., nitrosoalkanes; R−N=O), S-nitroso compounds (nitrosothiols; RS−N=O), N-nitroso compounds (e.g., nitrosamines, RN(−R’)−N=O), and O ...
Azo dyes are organic compounds bearing the functional group R−N=N−R′, in which R and R′ are usually aryl and substituted aryl groups. They are a commercially important family of azo compounds, i.e. compounds containing the C-N=N-C linkage. [1] Azo dyes are synthetic dyes and do not occur naturally. [2] [3] Most azo dyes contain only one ...
4-Fluoronitrobenzene is an organic compound with the formula FC 6 H 4 NO 2. It is one of three isomeric fluoronitrobenzenes. [2] A yellow oil, it is prepared from 4-nitrochlorobenzene using the Halex process : 4-Fluoronitrobenzene can be hydrogenated to give 4-fluoroaniline, [3] which is a precursor to the fungicide fluoroimide.
