General description

4-Nitroanisole undergoes photochemical nucleophilic aromatic substitution by hydroxide ion to form 4-methoxyphenol and 4-nitrophenol.

Application

4-Nitroanisole was used as probe to determine Π* of Kamlet-Taft solvent parameters and high pressure and supercritical water in the temperature range of 16-420 °C. 4-Nitroanisole was used as carbon and energy supplement for the isolation of Rhodococcus strains.

Biochem/physiol Actions

4-Nitroanisole is O-demethylated to 4-nitrophenol by human liver microsomes.

A temperature-sensitive photochemical nucleophilic aromatic substitution on 4-nitroanisole by a hydroxide ion in homogeneous solutions, in a two-phase system under phase-transfer catalysis conditions, and in the microwave field is reported. It was found that reaction regioselectivity dramatically changes with temperature
