What are 2-Bromo-4-t-butyl-1-fluorobenzene synthesis methods?

To prepare 2-bromo-4-tert-butyl-1-fluorobenzene, the method of organic synthesis is often followed.

First, it can be started from compounds containing benzene rings. If p-tert-butylphenol is used as raw material, the following steps are taken:
First, the hydroxyl group of p-tert-butylphenol is converted into a fluorine atom with hydrofluoric acid. In this step, suitable reaction conditions and catalysts are selected to make the phenolic hydroxyl group react with hydrofluoric acid at a specific temperature and pressure. After the nucleophilic substitution process, the oxygen atom of the phenolic hydroxyl group is attacked by fluoride ions to form p-tert-butylfluorobenzene. The key to this step is to control the reaction temperature and the amount of hydrofluoric acid < Br > Then, p-tert-butyl fluorobenzene and bromine are catalyzed by an appropriate catalyst such as iron or iron salt to undergo electrophilic substitution reaction. Bromine positive ions are attracted by the electron cloud of the benzene ring and attack the benzene ring. According to the positioning rules, because tert-butyl is an ortho-para-localization group, the fluorine atom also has a certain localization effect, and finally the ortho-position is introduced into the bromine atom, so 2-bromo-4-tert-butyl-1-fluorobenzene is obtained. This step should pay attention to the amount of bromine and the reaction time to prevent the formation of polybrominated products.

Second, p-fluorobenzyl ether can also be used as the starting material. First, the tert-butyl chloride and anhydrous aluminum trichloride were used as catalysts to carry out the Fu-gram alkylation reaction, and the tert-butyl group was introduced into the benzene ring para-position to obtain 4-tert-butyl-1-fluorobenzyl ether. This reaction needs to be carried out in an anhydrous environment to ensure the activity of the catalyst.
Then, 4-tert-butyl-1-fluorobenzyl ether was treated with hydrobromic acid to convert the methoxy group into a bromine atom. After the nucleophilic substitution reaction, 2-bromo-4-tert-butyl-1-fluorobenzene was finally obtained. This step requires controlling the concentration of hydrobromic acid and the reaction temperature to make the reaction proceed smoothly.

All synthesis methods require fine regulation of reaction conditions, taking into account factors such as the selection of raw materials, the amount of reagents, the activity of catalysts, and the temperature and time of the reaction, in order to effectively improve the yield and purity of the target product.

During transportation, temperature and vibration must also be strictly controlled. Avoid large fluctuations in temperature and prevent the stability of compounds from being affected by temperature problems. The driving process should be as smooth as possible to reduce vibration and bumps to prevent the compound from causing accidents due to excessive vibration.

In addition, transportation and storage personnel must be professionally trained to be familiar with the characteristics of 2-bromo-4-tert-butyl-1-fluorobenzene and emergency treatment methods. In the event of an emergency such as a leak, they can respond quickly and correctly to reduce the harm.
