Anisole, or methoxybenzene, is an organic compound with the formula CH 3 OC 6 H 5. It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances .
Its chemical names are based on considering the structure as either an acetyl (methyl-ketone) analog of anisole. Other names It can also be seen as a methyl ether analog of acetophenone. Acetanisole is found naturally in castoreum, the glandular secretion of the beaver. [1]
Anisole (C 6 H 5 OCH 3) is the simplest phenol ether, and is a versatile precursor for perfumes and pharmaceuticals. [1] Vanillin and ethylvanillin are phenol ether derivatives commonly utilized in vanilla flavorings and fragrances, while diphenyl ether is commonly used as a synthetic geranium fragrance.
4-Bromoanisole forms a Grignard reagent, [1] which reacts with phosphorus trichloride to give tris(4-methoxyphenyl)phosphine: . 3 CH 3 OC 6 H 4 MgBr + PCl 3 → (CH 3 OC 6 H 4) 3 P + 3 MgBrCl
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Butylated hydroxyanisole (BHA) is a synthetic, waxy, solid petrochemical.Its antioxidant properties have caused it to be widely used as a preservative in food, food packaging, animal feed, cosmetics, pharmaceuticals, rubber, and petroleum products. [3]
Thioanisole is an organic compound with the formula CH 3 SC 6 H 5.It is a colorless liquid that is soluble in organic solvents. It is the simplest alkyl–aryl thioether. The name indicates that this compound is the sulfur analogue—the thioether rather than the oxygen-centered ether—of anisole.
Lawesson's reagent is commercially available. It can also be conveniently prepared in the laboratory by heating a mixture of anisole with phosphorus pentasulfide until the mixture is clear and no more hydrogen sulfide is formed, [2] then recrystallized from toluene or xylene. Samples give a strong odor of hydrogen sulfide owing to partial ...
