用途有機合成原料。
使用4-Bromoanisole finds application as an intermediate in synthetic chemistry. It is used in the preparation of aryl 1,3-diketones and ethyl 4-methoxycinnamate. It is a used as a brominating reagent. Further, it is used in Suzuki coupling reaction with phenylboronic acid as well as in Heck reaction.
一般的な説明4-Bromoanisole is a useful brominating reagent. It is formed as reaction product in the reaction between HOBr and anisole. Suzuki coupling of 4-bromoanisole with phenylboronic acid catalyzed by palladium pincer complexes has been studied. Heck Reaction of 4-bromoanisole with ethyl acrylates in room-temperature ionic liquids is reported to afford ethyl 4-methoxycinnamate.
製造方法4-Bromoanisole is obtained by reacting p-bromophenol with dimethyl sulfate.
純化方法Crystallise the anisole by repeated partial freezing, then distil it under reduced pressure. [Beilstein 6 III 741, 6 IV 1044.]

化学的特性4-Bromoanisole is a colourless to pale yellow oily liquid with a pleasant smell similar to that of anise seed. Insoluble in water, soluble in ethanol, ether and chloroform. It is one of three isomers of bromoanisole, the others being 3-bromoanisole and 2-bromoanisole. It is the precursor to many 4-anisyl derivatives.
定義ChEBI: 4-bromoanisole is a monomethoxybenzene carrying a bromo substituent at position 4. It is a monomethoxybenzene and an organobromine compound.
