What are the physical properties of 2-Fluoro-6-Methoxybenzeneboronic Acid?
2-Fluoro-6-methoxyphenylboronic acid, which is white to pale yellow crystalline powder. Its melting point is within a certain range, usually between 120 ° C and 125 ° C. This property is essential for the identification and purification of this compound.
In terms of solubility, it shows different performance in common organic solvents. In alcoholic solvents such as methanol and ethanol, it has better solubility, because the boric acid group in the molecule can form hydrogen bonds with the alcohol hydroxyl group, which promotes dissolution. However, in non-polar solvents such as hexane and toluene, the solubility is poor, due to the relatively small polar part of the molecule and the weak interaction with non-polar solvents.
In terms of stability, under conventional storage conditions, if the environment is dry and the temperature is moderate, it can remain relatively stable. However, when it encounters strong oxidizing agents or strong bases, it is easy to react and cause structural changes. For example, in a strong base environment, boric acid groups will react with hydroxide ions to form corresponding borates.
Because its structure contains boron atoms and benzene rings, it has certain reactivity and is widely used in the field of organic synthesis. It can participate in many important organic reactions, such as the Suzuki reaction, to build carbon-carbon bonds and realize the synthesis of complex organic molecules.
2-Fluoro-6-Methoxybenzeneboronic the chemical properties of Acid
2-Fluoro-6-methoxyphenylboronic acid is an important chemical reagent in the field of organic synthesis. Its chemical properties are unique and it plays a key role in many chemical reactions.
When it comes to acidity, the substance is weakly acidic, because the boric acid part can give protons under suitable conditions. In its structure, the outer electrons of the boron atom are in an electron-deficient state, so it can accept electron pairs, showing Lewis acidic properties. This acidity makes it suitable for some nucleophilic substitution reactions and catalytic reactions. It can be used as a catalyst or reaction intermediate to help the reaction proceed smoothly.
In terms of stability, 2-fluoro-6-methoxyphenylboronic acid is relatively stable under normal conditions. However, it is quite sensitive to humidity and easily reacts with water. If not stored properly and exposed to water, the boric acid group may undergo changes such as hydrolysis, which in turn affects its chemical activity and purity. Therefore, it should be stored in a dry environment and properly sealed.
In terms of reactivity, the presence of fluorine atoms and methoxy groups significantly affects the distribution of molecular electron clouds. Fluorine atoms have a strong electron-absorbing effect, and methoxy groups have a electron-giving effect. Together, the electron cloud density on the benzene ring changes. In this way, the electron cloud density at a specific location in the benzene ring changes, making the substance more susceptible to reacting with electrophilic or nucleophilic reagents. For example, 2-fluoro-6-methoxyphenylboronic acid and halogenated aromatic hydrocarbons can form biphenyl compounds efficiently under the action of suitable catalysts and bases in an important carbon-carbon bond-building reaction such as the Suzuki coupling reaction. This reactivity provides a powerful tool for organic synthetic chemists to construct complex organic molecular structures, and has wide application prospects in many fields such as medicinal chemistry and materials science.
What is the synthesis method of 2-Fluoro-6-Methoxybenzeneboronic Acid?
The synthesis method of 2-fluoro-6-methoxyphenylboronic acid can follow the following steps.
First, 2-fluoro-6-methoxybromobenzene is used as the starting material. This raw material and magnesium chips are mixed in anhydrous ether or tetrahydrofuran in an organic solvent under nitrogen protection to initiate the Grignard reaction. The magnesium chips need to be pretreated to ensure their good activity. During the reaction, slowly add the solution of 2-fluoro-6-methoxybromobenzene dropwise, maintain a moderate temperature, such as 30-40 ° C, and continue to stir to make the reaction fully proceed to generate the corresponding Grignard reagent 2-fluoro-6-methoxyphenylmagnesium bromide.
Next, the prepared Grignard reagent is slowly dropped into the anhydrous ether or tetrahydrofuran solution of trimethyl borate at a low temperature, such as -78 ° C. After adding it dropwise, gradually heat it up to room temperature, and continue to stir the reaction number to make the substitution reaction of borate ester complete. At this time, trimethyl borate reacts with Grignard reagent to form 2-fluoro-6-methoxyphenylborate.
Furthermore, after the reaction is completed, an appropriate amount of dilute hydrochloric acid solution is added to the system for hydrolysis. The concentration of dilute hydrochloric acid should be controlled within a certain range, such as 1-2 mol/L. During the hydrolysis process, trimethyl 2-fluoro-6-methoxyphenylborate is converted into the target product 2-fluoro-6-methoxyphenylboronic acid. After the hydrolysis is completed, the organic phase is extracted with an organic solvent such as ethyl acetate.
Finally, the organic phase is dried with anhydrous sodium sulfate, filtered to remove the desiccant, distilled under reduced pressure to remove the organic solvent, and then purified by column chromatography or recrystallization to obtain pure 2-fluoro-6-methoxyphenylboronic acid.
Alternatively, 2-fluoro-6-methoxyiodobenzene can also be used to replace 2-fluoro-6-methoxybromobenzene. According to the above similar method, 2-fluoro-6-methoxyphenylboronic acid can also be prepared. However, the activity of iodobenzene is higher, and the reaction conditions may be slightly adjusted to achieve the best synthetic effect.
What is the price range of 2-Fluoro-6-Methoxybenzeneboronic Acid in the market?
2-Fluoro-6-methoxyphenylboronic acid is in the market, and its price range is difficult to determine. The price of this chemical often changes for various reasons.
First, the amount of quantity has a great impact on the price. If the buyer wants a wide quantity, the seller may offer a discount for the benefit of the product, and the price will be slightly reduced. On the contrary, if the quantity is small, the seller may worry about the profit, and the price may be slightly higher.
Second, the quality of the product is also the key to the price. Those with high purity often have a higher price than those with poor purity due to the preparation process or complexity, and the cost of materials and labor hours.
Third, the supply and demand of the city determines the rise and fall of the price. If there are many people who need this product at any time, and the supply is limited, the price will tend to rise; if the supply exceeds the demand, the seller will sell it quickly, and the price may drop.
Fourth, the place of origin is also related to the supplier. If it is shipped from a distance, the price may increase due to the freight, etc.; different suppliers, due to their different costs and policies, have different prices.
Looking at the past market conditions, the price of 2-fluoro-6-methoxyphenylboronic acid ranges from tens of thousands to hundreds of thousands per ton. However, this is only an approximate number, and it changes with the market. The current price should be confirmed by consulting the chemical dealers in detail. Its price fluctuates frequently and is not static. Buyers should check the market conditions to get a good price.
