What are the synthesis methods of (s) -2,4-dichloro-alpha - (chloromethyl) -benzyl methanesulfonate?
To prepare (s) -2,4 -difluoro -α - ( fluoromethyl) -acetophenone ester, the method is as follows:
First take an appropriate amount of acetophenone, place it in a clean reactor, and cool it at low temperature to a specific temperature range, about -10 ° C to 0 ° C. In this low temperature environment, slowly add fluorine-containing reagents, such as fluoromethylating reagents, and stir while adding droplets to allow the reaction to proceed uniformly. This process requires careful control of the dropwise rate to prevent the reaction from being too violent.
After the fluoromethylation reaction is completed, heat up to an appropriate temperature, about 20 ° C to 30 ° C, and then add a difluoride reagent to promote the difluoride substitution reaction. This step also requires close attention to the reaction process. The degree of reaction can be controlled by monitoring the physical or chemical changes of the reaction system, such as observing color, measuring pH, etc.
When the difluorine substitution reaction reaches the expected level, transfer the reaction system to another container, add a specific esterification reagent, and carry out the esterification reaction in the presence of an appropriate catalyst. The amount of catalyst needs to be precisely controlled, generally 1% - 5% of the total reactant. The esterification reaction temperature is maintained at 40 ° C to 50 ° C, and the reaction continues for several hours until the reaction is complete.
After the reaction is completed, conventional separation and purification methods such as distillation, extraction, recrystallization, etc. are used to remove impurities in the reaction system, and finally the pure product of (s) -2,4 -difluoro -α - ( fluoromethyl) -acetophenone ester can be obtained. The whole synthesis process requires strict control of the reaction conditions of each step to ensure the purity and yield of the product.

What are the precautions for (s) -2,4-dichloro-alpha - (chloromethyl) -benzyl methanesulfonate during storage and transportation?
(S) -2,4 -dioxy -α - （ methoxymethyl) -furanoacrylate should pay attention to the following things during storage and transportation:
First, the control of temperature and humidity. This compound is quite sensitive to temperature and humidity. High temperature is easy to cause its decomposition and deterioration, damaging its chemical properties and quality. Therefore, storage should be selected in a cool and dry place, the temperature should be maintained at 5 ° C to 25 ° C, and the humidity should be controlled at 40% to 60%. When transporting, you should also pay attention to the ambient temperature and humidity. When taking cooling measures in hot weather, humid places should be moisture-proof.
Second, protection from light. It is photosensitive, and light will cause luminescent chemical reactions, causing its structure to change. When storing, it should be placed in a brown bottle or a shading container, away from direct light. During transportation, it is also necessary to ensure that the transportation tool can be effectively shaded.
Third, avoid vibration and collision. The substance may react dangerously under vibration or collision. When storing, it should be placed safely to avoid overstacking and dumping collisions. When transporting, buffer protection should be done to ensure that the packaging is stable and reduce the impact of vibration.
Fourth, isolated storage. Do not mix with oxidants, acids, alkalis and other substances. Because of its active chemical properties, contact with these substances is prone to violent reactions, resulting in safety accidents. Storage warehouses should be divided and classified, and different types of chemicals should be isolated during transportation.
Fifth, the packaging is tight. The packaging needs to ensure a good seal to prevent leakage. Leakage will not only cause material loss, pollute the environment, but also may cause safety risks in some cases. The packaging should be carefully checked before storage, and it should be confirmed again before transportation. If the packaging is damaged, it needs to be replaced in time.
