Likewise, it is also prone to oxidation: while freshly purified aniline is an almost colorless oil, exposure to air results in gradual darkening to yellow or red, due to the formation of strongly colored, oxidized impurities. Aniline can be diazotized to give a diazonium salt, which can then undergo various nucleophilic substitution reactions.
The Boyland–Sims oxidation is the chemical reaction of anilines with alkaline potassium persulfate, which after hydrolysis forms ortho-hydroxyl anilines. [ 1 ] [ 2 ] [ 3 ] The reaction is generally performed in water at room temperatures or below, using equimolar quantities of reagents.
Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds. The K and B bands arise from π to π* transitions as a result of the a group containing multiple bond being attached to the benzene ring. When dissolved in ethanol, λ max for aniline is 230 nm, but in dilute aqueous acid λ max is 203 nm ...

Diphenylamine is an organic compound with the formula (C 6 H 5) 2 NH. The compound is a derivative of aniline, consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities. [5]
Studies have demonstrated that the glucose-alanine cycle may play a direct role in regulation of hepatic (liver) mitochondrial oxidation, particularly during periods of extended fasting. [9] Hepatic mitochondrial oxidation is a key process in the metabolism of glucose and fatty acids, involving the Citric Acid Cycle and oxidative ...
Monoamine oxidases (MAO) (EC 1.4.3.4) are a family of enzymes that catalyze the oxidation of monoamines, employing oxygen to clip off their amine group. [1] [2] They are found bound to the outer membrane of mitochondria in most cell types of the body.
Dimethylaniline undergoes many of the reactions expected for an aniline, being weakly basic and reactive toward electrophiles. [6] It is nitrated to produce tetryl, a derivative with four nitro groups which was once used as explosive. In acidic solution, the initial nitration gives 3-nitrodimethylaniline. [7]
