What are the synthesis methods of (3-fluoro-4 '-propyl [biphenyl] -4-yl) boronic acid

There are several common methods for the synthesis of (3-fluoro-4 '-propyl [biphenyl] -4-yl) boric acid as follows.

First, a suitable halogenated aromatic hydrocarbon is used as the starting material. First, the halogenated aromatic hydrocarbon is reacted with a metal reagent, such as a lithium reagent, at a low temperature and under severe conditions of no water and no oxygen to form an organolithium compound. This reaction requires fine control of temperature and reaction time. A slight difference in the pool can easily lead to side reactions. Then, the generated organolithium compound is reacted with borate ester reagents. After hydrolysis, the target product (3-fluoro-4 '-propyl [biphenyl] -4-yl) boric acid can be obtained. Although the steps of this method are relatively clear, the requirements for reaction conditions are quite high, and the metal reagents are active, so the operation needs to be very cautious.

Second, the coupling reaction catalyzed by palladium. Select a halogenated aromatic hydrocarbon containing suitable substituents and borate esters or boric acid derivatives as raw materials, and react under the combined action of palladium catalysts, ligands and bases. The activity and selectivity of palladium catalysts are crucial, and the structure of ligands also significantly affects the reaction process. This reaction usually requires stirring in a suitable solvent at a certain temperature. The advantage of this approach is that the reaction conditions are relatively mild and the yield is relatively considerable. However, the high cost of palladium catalysts limits its large-scale application to a certain extent.

Third, synthesize by Grignard reagent method. Halogenated aromatics are prepared into Grignard reagents. This process requires magnesium chips as reactants in anhydrous ether or tetrahydrofuran solvents. The prepared Grignard reagent is then reacted with borate esters, and subsequent hydrolysis treatment can also obtain (3-fluoro-4 '-propyl [biphenyl] -4-yl) boric acid. However, Grignard reagents are extremely sensitive to water and air, and the preparation and reaction processes require strict isolation of water vapor and oxygen.

What are the physical properties of (3-fluoro-4 '-propyl [biphenyl] -4-yl) boronic acid

(3-Fluoro-4 '-propyl [biphenyl] -4-yl) boric acid, the properties of this substance are worth exploring. Its color may be pure white, and its shape is slightly crystalline. It looks like powder, delicate and uniform. Under normal temperature and pressure, it exists stably, and seems to have a quiet nature.

When it comes to the melting point, it has been explored by many parties and is about a specific temperature range. This temperature is the boundary point where it changes from solid to liquid, highlighting the change of its internal molecular structure under the action of heat. Its solubility, in specific organic solvents, such as alcohols and ethers, can gradually dissolve and homogenize, just like raindrops entering a lake, and they blend seamlessly. This is due to the interaction between molecular forces and solvents.

However, in water, the solubility is inferior, just like oil and water are difficult to mix, due to the difference between molecular polarity and water polarity. And if this substance is in the air, if it is not properly protected, or gradually responds to trace water vapor and oxygen, although it becomes slow, it will melt for a long time, so it often needs to be sealed and stored in a cool place to ensure its purity. Its density also has a specific value, which is related to the ratio of its mass to volume. It is an important parameter in practical applications, such as material ratio, separation and purification.

What is the price range of (3-fluoro-4 '-propyl [biphenyl] -4-yl) boronic acid in the market?

I don't know the price range of (3-fluoro-4 '-propyl [biphenyl] -4-yl) boric acid in the market. The price of this compound often varies due to many reasons, such as the quality, the amount purchased, the situation of supply and demand, and the difficulty of preparation. If the quality is high and the purchase quantity is quite large, the price may be slightly lower; if the quality is normal and the purchase quantity is very small, the price is afraid of high. In addition, the market supply and demand are unbalanced, and the demand exceeds the supply, the price will rise; if the supply exceeds the demand, the price will be depressed. Furthermore, if the synthesis of this compound is complicated and the raw materials are rare, it will also cause its price to be high. Due to the lack of exact market data, it is difficult to determine its price range.
