What are the synthesis methods of 1-chloro-3-iodine-5- (trifluoromethyl) benzene?

To prepare 1-bromo-3- (trifluoromethyl) benzene, you can do it from the following methods:

First, m-trifluoromethylaniline is used as the raw material. First, m-trifluoromethylaniline is diazotized with sodium nitrite and hydrobromic acid at low temperature to obtain diazonium salts. This step must be controlled to prevent the decomposition of diazonium salts. Subsequently, cuprous bromide is added, and a Sandmeier reaction occurs. The diazonium group is replaced by a bromine atom to obtain the target product 1-bromo-3- (trifluoromethylaniline) benzene. This method is slightly complicated, but the yield is acceptable, and the raw material m-trifluoromethylaniline is relatively easy to obtain.

Second, m-trifluoromethylbenzoic acid is used as the starting material. First, m-trifluoromethylbenzoic acid is reacted with dichlorosulfoxide to convert it into m-trifluoromethylbenzoyl chloride. This reaction needs to be carried out in a dry environment to avoid hydrolysis of the product. Then, using palladium carbon as the catalyst and hydrogen as the reducing agent, Rosemond reduction is carried out to reduce m-trifluoromethylbenzoyl chloride to m-trifluoromethylbenzaldehyde. Finally, using a brominating agent, such as N-bromosuccinimide (NBS), under the action of light or initiator, the benzyl position of m-trifluoromethylbenzaldehyde is brominated, and then through a series of conversions, 1-bromo-3- (trifluoromethyl) benzene can be obtained. There are many steps in this path, but the reaction conditions of each step are relatively mild and do not require strict equipment.

Third, m-chlorotrifluorotoluene is used as the raw material. In a suitable reaction system, magnesium metal is added to make Grignard reagent. After that, an appropriate amount of brominating reagents, such as 1,2-dibromoethane, are added to the system, and through a series of reactions, 1-bromo-3- (trifluoromethyl) benzene can also be obtained. This method takes advantage of the activity of Grignard reagents, and the reaction is more efficient. However, the preparation of Grignard reagents requires an anhydrous and oxygen-free environment, and the operation requirements are relatively high.

What are the physical properties of 1-chloro-3-iodine-5- (trifluoromethyl) benzene

3 - (triethylmethyl) naphthalene, its physical properties are as follows:

This substance is mostly solid at room temperature, with a certain crystalline form, regular crystal form, and hard texture. Its melting point is quite high, and it needs a higher temperature to melt into a liquid state. Due to the strong force between molecules, more energy is required to destroy the lattice structure.

Looking at its appearance, it is mostly white or nearly white, with a pure color. It is often shown in crystalline powder or block shape, with a certain luster, but it is not as dazzling as a metal, but it is a soft luster unique to organic compounds.

When it comes to density, compared to water, its density is slightly higher, so if it is put into water, it will sink to the bottom of the water. This is due to the tight accumulation of molecules and the large mass per unit volume.

In terms of solubility, it is extremely difficult to dissolve in water, because its molecular polarity is weak, and the force between water molecules is small, making it difficult to form a stable mixed system with water. However, in organic solvents, such as benzene, toluene and other non-polar or weakly polar solvents, the solubility is quite good, and it can be miscible with them to form a uniform solution. Due to the principle of "similar miscibility", the molecular structure is similar to the polarity.

Volatility is very small. At room temperature and pressure, the tendency of molecules to escape from the liquid surface and enter the gas phase is small. Due to the strong intermolecular force, the molecules are bound in the condensed phase and are not easy to volatilize into the air. This property makes the substance relatively stable and not easy to be lost due to volatilization

What are the chemical properties of 1-chloro-3-iodine-5- (trifluoromethyl) benzene

Triethylamino silicon is quite rich in chemical properties.

This substance is alkaline. Because nitrogen atoms do not share electron pairs and can accept protons, it is easy to react with acids in an acidic environment to form corresponding salts. For example, when exposed to hydrochloric acid, hydrochloride salts will be formed. This property can be used as an acid binding agent in many organic synthesis reactions to neutralize the acid generated by the reaction and promote the reaction to proceed in the desired direction.

Triethylamino silicon also exhibits nucleophilicity. The electron cloud density on the nitrogen atom is high, allowing the entire group to have nucleophilic ability and be able to attack electrophilic reagents. Like in some nucleophilic substitution reactions, it can participate as a nucleophilic reagent to react with electrophilic substrates such as halogenated hydrocarbons to achieve the introduction or transformation of functional groups.

And, the silicon atoms in the substance make it possible to participate in silicon-related reactions under specific conditions. For example, when there are suitable catalysts and reaction conditions, silicon atoms can undergo hydrolysis, and then condensate to form silicon-oxygen bonds, generating silicon-containing polymers or silicone-like compounds with different structures and properties, which is of great significance in the preparation of silicone materials.

In addition, triethylamine silicon has a certain surface activity due to its triethylamine group and silicon group. It can be adsorbed on the surface of certain materials to change the surface properties of materials, such as improving the wettability of materials and improving the compatibility of materials with other substances. It is used in coatings, adhesives, and other fields.

What are the precautions for storing and transporting 1-chloro-3-iodine-5- (trifluoromethyl) benzene?

When storing and transporting triethyl ether, pay attention to various matters.

First, it is related to storage. The place where this ether is hidden must be cool and well ventilated. Because of its flammability, if the temperature in the place is too high or the ventilation is not smooth, it is easy to cause combustion and explosion in case of open flames and hot topics. In the warehouse, it should be kept away from fire and heat sources. Explosion-proof lighting facilities and ventilation equipment should be used, and tools that do not generate sparks should be used for operation. In addition, the ether should be stored separately from oxidizing agents and acids, and should not be mixed to prevent violent chemical reactions from occurring and causing danger.

Second, about transportation. Before transportation, it is necessary to ensure that the packaging is complete and the loading is safe. Vehicles used for transportation should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. During driving, it is necessary to prevent exposure to the sun, rain and avoid high temperature. When transporting by road, it is necessary to follow the prescribed route and do not stop in residential areas and densely populated areas. When transporting by rail, it is also not allowed to slip away. During transportation, escorts need to pay close attention to the condition of the goods. Once any abnormality is detected, appropriate measures should be taken immediately.

All those who engage in the storage and transportation of this ether should be familiar with its dangerous characteristics and emergency treatment methods, and strictly abide by relevant safety regulations, so as to ensure the safety of storage and transportation.
