To prepare L-bromo-4- (difluoromethoxy) benzene, there are two common methods. One is to use 4-hydroxybenzene bromide as the starting material and obtain it through halogenation reaction. First, 4-hydroxybenzene bromide is co-placed with a base in a suitable organic solvent, such as dimethylformamide, to convert the phenolic hydroxyl group into phenoxy anion to enhance its nucleophilicity. Then slowly add difluoromethyl halides, such as difluoromethyl bromide. In this process, the phenoxy anion nucleophilic attacks the carbon atom of the difluoromethyl halide, and the halogen ion leaves, then the target product L-bromo-4- (difluoromethoxy) benzene is formed. The reaction conditions are mild and easy to operate. However, it is necessary to pay attention to the selection of halide and the control of reaction temperature and time to prevent side reactions.
The second is to use 4-bromoanisole as raw material, first brominate, introduce bromine atoms at the para-position of the benzene ring to obtain 4-bromo-1-methoxy-2-bromobenzene. Then the methoxy group is converted to difluoromethoxy by nucleophilic substitution reaction. Difluoromethylation reagents, such as difluoromethyltrimethylsilane, often react with 4-bromo-1-methoxy-2-bromobenzene in the presence of bases and catalysts. The base can take the proton of difluoromethyltrimethylsilane to form difluoromethyl anion, which acts as a strong nucleophilic agent to attack the carbon atom connected to the methoxy group on the benzene ring, and the methoxy group leaves, and finally obtains L-bromo-4- (difluoromethoxy) benzene. This path has a little more steps, but the raw materials are easy to obtain, the reaction selectivity of each step is acceptable, and the optimized conditions can also obtain higher yields. In short, when preparing this compound, it is necessary to weigh the availability of raw materials, cost and reaction conditions and choose an appropriate synthesis method.

For L-bromo-4- (difluoromethoxy) benzene, all kinds of matters should not be ignored during storage and transportation.
This is an organic compound, sexual or active. When stored, the first environment. It should be placed in a cool, dry and well-ventilated place. If it encounters high temperature or humidity, it is afraid of qualitative change. High temperature can promote its volatilization, or accelerate the reaction, damaging its quality; moisture can easily lead to hydrolysis and other changes, damaging its structure.
Also need to pay attention to isolation from other substances. Do not store and transport with oxidants, strong acids, strong bases, etc. Due to its chemical properties, or react violently with such substances, risk of explosion. Such as oxidizing agents, with strong oxidizing properties, when encountering this compound, it may cause an oxidation reaction, generate heat and cause fire; strong acids and alkalis can also be neutralized and replaced with it to change its chemical properties.
Packaging is also a priority. When using airtight, corrosion-resistant devices. Airtight can prevent volatilization and moisture-proof gas intrusion; corrosion-resistant compounds or corrosive, can protect the integrity of the package. And on the package, the logo must be clearly marked, with its name, sex, danger, etc., in order to identify and prevent misoperation.
During transportation, drive steadily and slowly. Avoid bumps and vibrations to avoid package damage. And the means of transportation should also be clean, dry, and free of other residues and pollution. If the long-distance, but also need regular inspection, prevention. In this way, to ensure the safety of L-bromo-4- (difluoromethoxy) benzene storage and transportation.
