The synthesis of mesotrione [10] was first disclosed in patents [11] filed by ICI, who had acquired Stauffer in 1987. [12] 1,3-Cyclohexanedione is first reacted with the acid chloride of 4-(methylsulfonyl)-2-nitrobenzoic acid under conditions in which the enolic hydroxyl group of the diketone reacts to form the benzoylated derivative. In a ...
Schwartz's reagent is the common name for the organozirconium compound with the formula (C 5 H 5) 2 ZrHCl, sometimes called zirconocene hydrochloride or zirconocene chloride hydride, and is named after Jeffrey Schwartz, a chemistry professor at Princeton University.
4-Nitrochlorobenzene is the organic compound with the formula ClC 6 H 4 NO 2. It is a pale yellow solid. It is a pale yellow solid. 4-Nitrochlorobenzene is a common intermediate in the production of a number of industrially useful compounds, including antioxidants commonly found in rubber .
All organisms produce alcohol in small amounts by several pathways, primarily through fatty acid synthesis, [70] glycerolipid metabolism, [71] and bile acid biosynthesis pathways. [72] Fermentation is a biochemical process during which yeast and certain bacteria convert sugars to ethanol, carbon dioxide, as well as other metabolic byproducts.
4-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is a pale yellow solid. It is a precursor to 4-nitrobenzoyl chloride, the precursor to the anesthetic procaine and folic acid. It is also a precursor to 4-aminobenzoic acid. [6]
Cyanuric chloride is employed as a reagent in organic synthesis for the conversion of alcohols into alkyl chlorides, [8] and carboxylic acids into acyl chlorides: [9]. It is also used as a dehydrating agent, e.g. in the conversion of amides to nitriles, [10] and for the activation of carboxylic acids for reduction to alcohols.
Cyanogen bromide is a common reagent in organic synthesis. In most reactions, it acts as a source of electrophilic cyanogen and nucleophilic bromide; carbocations preferentially attack the nitrogen atom. [4] In the presence of a Lewis acid, it cyanidates arenes. [9] BrCN converts alcohols to cyanates; amines to cyanamides or dicyanamides. [4]
Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
