What are the synthesis methods of 2-amino-5-chloro-2 '-fluorobenzophenone?

The synthesis method of 2-amino-5-chloro-2 '-fluorobenzophenone has been known for a long time, and after years of precipitation, many parties have obtained it. I would like to help you with this detailed description.

First, appropriate halogenated aromatics are used as starting materials. Halogenated aromatics and corresponding metal reagents, such as magnesium reagents, are prepared into Grignard reagents. This Grignard reagent is abnormally active and can react with carbonyl-containing compounds, such as 2-fluorobenzoyl chloride, for nucleophilic addition. This reaction needs to be carried out in a harsh environment without water and oxygen to ensure a smooth reaction, and anhydrous ether or tetrahydrofuran are often used as solvents to facilitate the reaction. After the reaction is completed, the precursor of the target product can be obtained through the steps of hydrolysis, separation and purification. Subsequently, the precursor is subjected to an amination reaction. Commonly used amination reagents such as ammonia water and amine compounds, under suitable temperature and pressure conditions, promote the amino group to replace the group at a specific position, and finally obtain 2-amino-5-chloro-2 '-fluorobenzophenone.

Second, benzoylation can also be used as the initial step. Using 5-chloro-2-aminobenzoic acid as raw material, acylation occurs with 2-fluorobenzoyl chloride in an inert solvent such as dichloromethane under the action of a condensing agent, such as dicyclohexyl carbodiimide (DCC). This reaction can build the basic skeleton of benzophenone. After the reaction is completed, the product can be further purified through a series of post-treatments, such as removal of by-products of the condensing agent, extraction, recrystallization, etc.

Furthermore, it can also be synthesized through a palladium-catalyzed cross-coupling reaction. Using benzene derivatives containing halogen atoms and benzene derivatives containing borate esters or boric acids as raw materials, in the presence of palladium catalysts such as tetra (triphenylphosphine) palladium (Pd (PPh)), and bases, a coupling reaction occurs in a suitable solvent. This method can precisely construct carbon-carbon bonds and has high selectivity for substrates. Subsequently, the product is subjected to appropriate functional group transformation to introduce amino groups and other desired substituents, and finally synthesize 2-amino-5-chloro-2 '-fluorobenzophenone.

Although there are many paths for this synthesis, each has its own advantages and disadvantages. Experimenters need to choose carefully according to their own conditions, the availability of raw materials, and the purity requirements of the product.

What are the physical properties of 2-amino-5-chloro-2 '-fluorobenzophenone?

2-Amino-5-chloro-2 '-fluorobenzophenone is one of the organic compounds. Its physical properties are quite important and are related to many practical applications.

First of all, its appearance is often white to light yellow crystalline powder. The color is slightly yellow, just like the early autumn, the leaves are slightly yellow, with a little natural color rhyme. This appearance feature is an important sign at the beginning of substance identification. If people look at objects, their color shape is first seen, and this color shape is the key to preliminary identification.

Furthermore, its melting point is between 127-131 ° C. The melting point is similar to the critical state of a substance, such as ice in winter, which melts when exposed to temperature. This temperature is the boundary of ice melting. When this temperature range is reached, this compound gradually melts from the solid state to the liquid state. This property is an important basis for its purification, separation and identification process. Chemists want to distinguish its authenticity from pure and heterogeneous, and measure its melting point to know one or two.

Solubility is also an important physical property. It is slightly soluble in water, but it has a certain solubility in organic solvents such as dichloromethane, chloroform, tetrahydrofuran, etc. This difference in solubility is like the choice of residence of things, which is not liked in the "residence" of water, but prefers the "environment" of organic solvents. In organic synthesis, this property can provide guidance for the selection of suitable reaction solvents, so that the reaction can proceed smoothly, just like setting a suitable stage for chemical reactions.

Its density also has a specific value, although the exact data varies slightly according to the specific measurement conditions, it is roughly within a certain range. The value of density is related to the compactness of substances, such as stone and cotton, the compactness of stone, and the density is high; the looseness of cotton, the density is low. The density of this compound is also one of the factors to be considered in the mixing and separation of substances.

Looking at its stability, it is quite stable under normal temperature and pressure and dry environment. However, in case of strong light, hot topic or contact with specific chemical substances, it may change. This stability is just like human nature. In a peaceful environment, it is safe and will change in the event of external stimuli. When storing and transporting this compound, this characteristic should be fully considered, such as avoiding strong light and controlling temperature, so that it can maintain its original properties and not deteriorate.

2-Amino-5-chloro-2 '-fluorobenzophenone is an important chemical in organic synthesis. When using it, many things need to be paid attention to.

First of all, safety protection is of paramount importance. This chemical may be toxic and irritating to a certain extent. Be sure to wear appropriate protective equipment when contacting, such as protective gloves, goggles and lab clothes, to prevent it from coming into contact with the skin and eyes. In case of accidental contact, rinse with plenty of water immediately and seek medical attention according to the specific situation. The operation should be carried out in a well-ventilated environment, such as a fume hood, to prevent inhalation of its volatile gases. Because of its volatiles or irritation to the respiratory tract, long-term inhalation or damage to health.

Secondly, storage is also exquisite. Store in a cool, dry and ventilated place, away from fire sources and oxidants. Due to its relatively active chemical properties, the temperature and humidity of the storage environment should be strictly controlled when exposed to heat, open flame or oxidant, or cause violent reactions or even explosions.

Furthermore, precise operation is indispensable during use. Before taking it, be sure to confirm the required dosage to avoid waste and pollution. When weighing, use a precise weighing instrument to ensure accurate dosage, because the dosage may have a significant impact on the reaction result. Reaction conditions also need to be strictly controlled, such as temperature, reaction time and reactant ratio. Under different reaction conditions, the reaction process and product involved by this chemical may be very different, so the reaction conditions need to be carefully adjusted according to the specific reaction requirements to achieve the expected reaction effect.

In addition, the treatment of experimental waste cannot be ignored. The waste 2-amino-5-chloro-2 '-fluorobenzophenone and related reaction products generated by the experiment must not be discarded at will, and must be properly disposed of in accordance with relevant environmental protection regulations and laboratory waste treatment procedures to prevent pollution to the environment.

In summary, when using 2-amino-5-chloro-2 '-fluorobenzophenone, every step from safety protection, storage, operation to waste disposal needs to be treated with caution, so as to ensure the safety and smooth progress of the experiment, while avoiding adverse effects on personnel and the environment.
