What are the synthesis methods of 2,3,4-trifluorobenzene-1-sulfonyl chloride?

The synthesis method of 2% 2C3% 2C4-tribromobenzene-1-sulfonate bromoester has been known since ancient times. To obtain this substance, there are the following common methods.

First, you can start with benzene. First, by bromination, benzene and bromine are electrophilic substitution under the catalysis of iron or iron salts to obtain bromobenzene. Then bromine in sequence, so that bromine atoms are introduced into the benzene ring one by one, and finally 2% 2C3% 2C4-tribromobenzene. At this time, fuming sulfuric acid acts with it to connect the sulfonic acid group to a specific position in the benzene ring to obtain 2% 2C3% 2C4-tribromobenzene sulfonic acid. Then this sulfonic acid is reacted with a brominating agent. If phosphorus tribromide or phosphorus pentabromide is treated, the sulfonic acid group can be converted into sulfonyl bromide, resulting in 2% 2C3% 2C4-tribromobenzene-1-sulfonate bromide.

Second, there are also those who use specific halogenated aromatics as starting materials. If a suitable halogenated benzene derivative is found, some bromine atoms on the benzene ring are already in a suitable position, and the remaining bromine atoms can be introduced accurately through selective bromination, reaching a state of 2% 2C3% 2C4-tribromobenzene. The next step is the same as the previous method, first sulfonating, and then converting the sulfonic acid to sulfonyl bromide to complete the synthesis of 2% 2C3% 2C4-tribromobenzene-1-sulfonate bromide.

Third, organometallic reagents are also useful in this synthesis. For example, Grignard's reagent or lithium reagent can be used to interact with aromatics containing bromine and specific substituents, and the reaction steps can be cleverly designed to construct a 2% 2C3% 2C4-tribromobenzene structure. Then, through sulfonation and bromination steps, the final product is obtained. These methods have their own advantages and disadvantages. When operating in practice, it is necessary to choose carefully according to many factors such as the availability of raw materials, the difficulty of controlling the reaction conditions, and the high or low yield.

What are the precautions for storing and transporting 2,3,4-trifluorobenzene-1-sulfonyl chloride?

2% 2C3% 2C4-tribromobenzene-1-sulfonate sodium salt requires attention during storage and transportation.

First storage, this compound should be stored in a cool, dry and well-ventilated place. A cool environment can prevent its properties from changing due to excessive temperature. If it is overheated, it may cause adverse reactions such as decomposition, which will damage its quality. A dry environment is also crucial because it is afraid of moisture. Moisture is prone to deliquescence, or chemical reactions with moisture can cause material deterioration. Good ventilation can avoid the accumulation of harmful gases and ensure its chemical stability. At the same time, be sure to keep away from fire, heat and oxidants. Fire source heat source is easy to cause it to burn, and oxidants come into contact with it, or trigger a violent oxidation reaction, resulting in danger. This compound should also be stored separately from acids, alkalis and other incompatible substances to prevent mutual reaction.

As for transportation, relevant regulations and standards must be strictly followed. Appropriate packaging materials should be selected to ensure its sealing and corrosion resistance to prevent leakage. During transportation, it should be properly fixed to avoid collision and vibration, because it is subject to strong impact or vibration, or internal structural changes, which may cause danger. Transportation tools should also be kept clean, dry, and free of other impurities that may react with them. In addition, transportation personnel should be familiar with the characteristics of the compound and emergency treatment methods. In case of emergencies, they can respond quickly and properly to ensure the safety of personnel and the environment is not polluted.
