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.
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.
p-Phenylenediamine (PPD) is an organic compound with the formula C 6 H 4 (NH 2) 2.This derivative of aniline is a white solid, but samples can darken due to air oxidation. [1] It is mainly used as a component of engineering polymers and composites like kevlar.
The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}} See also [ edit ]
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 ...
Aniline reacts with acyl chlorides or carboxylic anhydrides to give anilides. For example, reaction of aniline with acetyl chloride provides acetanilide ( CH 3 −CO−NH−C 6 H 5 ). At high temperatures, aniline and carboxylic acids react to give anilides.
Acetanilide can be produced by reacting acetic anhydride with aniline: [7]. C 6 H 5 NH 2 + (CH 3 CO) 2 O → C 6 H 5 NHCOCH 3 + CH 3 COOH. The preparation used to be a traditional experiment in introductory organic chemistry lab classes, [8] but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially ...
p-Anisidine condenses readily with aldehydes and ketones to form Schiff bases, which absorb at 350 nm.This colorimetric reaction is used to test for the presence of oxidation products in fats and oils, an official method for detecting them by the American Oil Chemists' Society. [9]
