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 .
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.
Acetanisole is an aromatic chemical compound with an aroma described as sweet, fruity, nutty, and similar to vanilla. In addition acetanisole can sometimes smell like butter or caramel. [3]
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 ...
Currently Banwari Chemicals Pvt Ltd situated in Bhiwadi, Rajasthan, India is the leading manufacturer of anethole. It is prepared commercially from 4-methoxypropiophenone, [4] [10] which is prepared from anisole. [3]
Anisaldehyde is prepared commercially by oxidation of 4-methoxytoluene (p-cresyl methyl ether) using manganese dioxide to convert a methyl group to the aldehyde group. It can also be produced by oxidation of anethole , a related fragrance that is found in some alcoholic beverages, by oxidative cleavage of an alkene .
The Williamson reaction is of broad scope, is widely used in both laboratory and industrial synthesis, and remains the simplest and most popular method of preparing ethers. Both symmetrical and asymmetrical ethers are easily prepared. The intramolecular reaction of halohydrins in particular, gives epoxides.
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.
