3-Cyano-4-fluorophenylboronic acid is a crucial reagent in the field of organic synthesis. It has unique chemical properties and plays a key role in many organic reactions.
Looking at its structure, the cyano group and the fluorine atom are connected to the benzene ring and are accompanied by boric acid groups. Cyanyl is a strong electron-absorbing group, which can reduce the electron cloud density of the benzene ring and affect the reactivity and selectivity on the benzene ring. Fluorine atoms, due to their large electronegativity and small atomic radius, can not only change the molecular electron distribution, but also have a significant impact on molecular stability and biological activity. Boric acid groups have unique reaction characteristics and can participate in a variety of bonding reactions.
In chemical reactions, 3-cyano-4-fluorophenylboronic acid is often involved in typical boric acid-related reactions. One is the Suzuki coupling reaction, in which boric acid groups can be coupled with halogenated aromatics or olefins under palladium catalysis to form new carbon-carbon bonds, whereby complex organic molecular structures can be constructed, which is widely used in drug synthesis, materials science and other fields. Second, boric acid groups can complex with diol compounds to form stable cyclic borate esters, which may have applications in analytical chemistry and molecular recognition.
Furthermore, the presence of cyanyl groups and fluorine atoms will affect the physical and chemical properties of molecules. Cyanyl groups can enhance molecular polarity and affect the solubility and melting point of compounds. The introduction of fluorine atoms can improve the lipophilicity of molecules, which has a great impact on the biological activity and metabolic stability of compounds, which makes 3-cyano-4-fluorophenylboronic acid potentially valuable in drug development. Due to its lipophilicity, it has a positive effect on drug transmembrane transport and target binding.
Overall, 3-cyano-4-fluorophenylboronic acid has diverse chemical properties due to its unique structure, and has shown important application prospects in many fields such as organic synthesis, pharmaceutical chemistry, and materials science. It provides a powerful tool for researchers to create novel compounds and materials.

The synthesis of 3-cyano-4-fluorophenylboronic acid involves several approaches. One is to use 3-cyano-4-fluorobromobenzene as the starting material and react with n-butyllithium in a low temperature environment. In this process, the butyl part of n-butyllithium will replace the bromine atom to generate a highly active lithium reagent. Subsequently, the lithium reagent is reacted with borate esters (such as trimethyl borate), and the boron atom of the borate ester is combined with the lithium reagent. After the hydrolysis step, 3-cyano-4-fluorophenylboronic acid can be obtained. This method requires low temperature conditions to ensure the selectivity of the reaction and the stability of the active intermediate.
In addition, 3-cyano-4-fluorochlorobenzene can also be used as a starting material to react with diphenacol borate in a palladium-catalyzed system. The palladium catalyst can activate the carbon-chlorine bond of chlorobenzene to promote the coupling reaction of chlorobenzene with borate ester. This reaction condition is relatively mild, but the price of palladium catalyst is higher, which has a certain impact on the reaction cost. After the reaction is completed, the target product can also be obtained after appropriate post-treatment.
Another way is to use 3-cyano-4-fluoroaniline as a raw material, and the diazotization reaction is carried out first. Aniline is converted into diazonium salt, and then boron-containing reagents are added to replace the diazonium group with boron group to generate 3-cyano-4-fluorophenylboronic acid. This method step is slightly complicated, and the diazotization reaction conditions need to be precisely controlled to prevent side reactions from occurring.
All synthesis methods have advantages and disadvantages. In practical applications, the appropriate synthesis path needs to be carefully selected according to factors such as raw material availability, cost, and product purity.

3-Cyano-4-fluorophenylboronic acid, the price of this product in the market is difficult to say in a word. The change in its price is like an illusion in the wind and clouds, and it often varies according to various reasons.
First, the price varies depending on the source of production. If it comes from a factory with great quality, with its skill and quantity, it is expected that its price may be flat, and it can benefit many people. However, if it comes from a small workshop, the craftsmanship may not be exquisite, the quantity is also small, and the price may be high.
Furthermore, the trend of supply determines its price. There are many people in the market who need it, but the supply is small, and the price must go up; if the supply exceeds the demand, the merchant will sell his goods, and the price will go down.
In addition, the quality of good goods is related to the price. Those who are of high quality can respond to all strict requirements, and the price should be high; those who are of inferior quality, although cheap, are difficult to enter the eyes of those who are meticulous.
The cost of transportation is also a variable of the price. If the origin is far away and the transportation is difficult, the cost will be added to the price.
From a comprehensive perspective, if you want to know the exact price of 3-cyano-4-fluorophenylboronic acid, you should carefully observe the market conditions and consult the merchants before you can obtain its near-real price.

3-Cyano-4-fluorophenylboronic acid is an important reagent for organic synthesis. During storage and transportation, many matters need to be paid attention to.
First words storage, this compound should be stored in a cool, dry and well-ventilated place. Because of its certain chemical activity, high temperature and humidity can easily cause it to deteriorate. The temperature should be maintained at 2-8 ° C. If the environment is overheated, it may decompose, damaging its chemical structure and reducing its reactivity. Furthermore, it must be kept dry. Moisture can hydrolyze the boric acid group and cause it to fail. Therefore, a desiccant can be placed near the storage container to keep the environment dry.
As for transportation, there are also many points. It is necessary to ensure that the packaging is tight to prevent damage to the packaging due to vibration and collision. Because it may be dangerous to a certain extent, it needs to be disposed of in accordance with the relevant dangerous chemical transportation regulations. During transportation, temperature control is also the key, and the temperature fluctuation should not be too large. And avoid mixing with oxidizing agents, strong bases and other substances, because it may react violently with such substances, endangering transportation safety.
In short, the storage and transportation of 3-cyano-4-fluorophenylboronic acid is related to its quality and safety. It needs to be treated with caution and follow specific specifications and requirements to ensure its chemical stability and play its due role in subsequent organic synthesis reactions.
