Infobox references

4-Fluoronitrobenzene is an organic compound with the formula FC6H4NO2. It is one of three isomeric fluoronitrobenzenes.[2] A yellow oil, it is prepared from 4-nitrochlorobenzene using the Halex process:

O2NC6H4Cl + KF → O2NC6H4F + KCl

4-Fluoronitrobenzene can be hydrogenated to give 4-fluoroaniline,[3] which is a precursor to the fungicide fluoroimide.

Owing to the presence of the electron withdrawing nitro group, the fluoride is a good leaving group in fluoronitrobenzenes. Thus reaction with phenoxide gives the mononitrodiphenylether.[4]
