What are the synthesis methods of 4- (trifluoromethyl) quinoline-2-carboxylic acid?
To prepare 4 - (trifluoromethyl) benzoic acid - 2 - carboxylethyl ester, there are many methods, each with its own advantages and disadvantages. The following are several common methods.
First, aromatic hydrocarbons containing corresponding substituents are used as starting materials, and they are obtained by halogenation, cyanidation, hydrolysis and esterification. First, the aromatic hydrocarbons are halogenated under specific conditions and halogen atoms are introduced. This step needs to pay attention to the selectivity of the reaction and the control of conditions. Due to different halogenated reagents and reaction environments, the structure and yield of the product are greatly affected. Then cyanide is used to replace halogen atoms with cyanyl groups. The cyanidation reaction conditions are more severe, and suitable catalysts and solvent systems are required to ensure the smooth progress of the reaction. Then the cyanyl group is hydrolyzed to form a carboxyl group. The acid-base conditions of this process need to be precisely regulated to prevent excessive hydrolysis or other side reactions. Finally, the obtained carboxylic acid and ethanol are esterified under acid catalysis to obtain the target product. This method is a little complicated, but the raw materials are easy to obtain. The reaction conditions of each step are relatively mature, and it is widely used in industrial production.
Second, the coupling reaction strategy of transition metal catalysis is adopted. Select the appropriate aromatic halide or pseudo-halide, and the reagent containing trifluoromethyl and carboxyl ethyl ester-related structures, and couple it under the catalysis of transition metal catalysts such as palladium and nickel. This process requires extremely high activity and selectivity of the catalyst, and the reaction conditions also need to be carefully optimized, such as reaction temperature, ligand selection, etc The advantage of the coupling reaction is that the atom economy is high, and the carbon-carbon bond can be efficiently constructed, which is expected to improve the yield and purity of the product. However, the cost of catalysts is high, and some reactions require a strict anhydrous and anaerobic environment, which requires strict reaction equipment and operation.
Third, starting from compounds containing trifluoromethyl and carboxyl precursors, they are converted into the target product through specific rearrangements and substitutions. For example, some esters or amides with special structures are rearranged under specific reagents and conditions, so that the functional groups migrate and convert into the desired 4- (trifluoromethyl) benzoic acid-2-carboxyethyl ester structure. Such methods require delicate design of the structure of the starting material and unique reaction conditions. However, if properly designed, the reaction steps can be simplified and novel synthesis paths can be opened up.
All these synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively consider the availability of raw materials, cost, difficulty of reaction conditions, purity and yield of products and many other factors, and carefully choose the appropriate method.
What are the physicochemical properties of 4- (trifluoromethyl) quinoline-2-carboxylic acid?
The physical and chemical properties of 4- (triethyl) boric acid-2-naphthoic acid are particularly important. These two have their own characteristics and are related to many fields of application.
First, 4- (triethyl) boric acid, which is often colorless and transparent liquid, is relatively stable under normal temperature and pressure. Its boiling point is worth noting, and it usually boils within a specific temperature range. The definition of this temperature range is related to the separation and purification steps in chemical operations. And its solubility also has characteristics. It is soluble in some organic solvents, such as common ethers and aromatic hydrocarbon solvents, but it has poor solubility in water. This difference in solubility provides a basis for its application in different systems. < Br >
As for 2-naphthoic acid, the appearance is usually white to light yellow crystalline powder. The melting point is one of the important physical properties. When it reaches a certain temperature, it melts into a liquid state. The accurate determination of this melting point is of great significance for its refining and purity determination. Its acidity is slightly stronger than that of ordinary fatty acids, which is caused by the conjugation effect of naphthalene rings. Because of its acidity, it can neutralize with alkalis to form corresponding salts. And in organic solvents, the solubility varies depending on the type of solvent. The solubility is relatively large in alcohols and relatively small in alkane solvents.
The differences and characteristics of the physical and chemical properties of the two are widely used in organic synthesis, pharmaceutical chemistry, materials science and many other fields. When synthesizing new organic materials, the stability and solubility of 4- (triethyl) boric acid and the acidic and crystalline properties of 2-naphthoic acid can be used to construct compounds with specific structures and functions to meet the needs of different scenarios.
What is the price range of 4- (trifluoromethyl) quinoline-2-carboxylic acid in the market?
Wen Jun wants to know the price range of (triethyl) diol-2-naphthoic acid in the market, and I will report it in detail. However, the price of the market often varies according to the quality, the change of supply and demand, and the difference of time.
Looking at the past, if the quality is high and the supply is slightly thin, the price may be high; if the quality is flat and the supply is excessive, the price will drop.
As a common sense, the price is about tens to hundreds of dollars per gram. However, in case of fluctuations in the market, the price may exceed this range. If the demand is large, but the output is small, the price may jump by hundreds of dollars per gram; conversely, if the production is prosperous and the demand is weak, the price may drop to tens of dollars per gram.
And the different vendors, the price is also different. Big Jia's goods, or because of high quality, good reputation and high price; small business products, or for quick sale and slightly cheaper.
To get a price confirmation, when you visit the cities in person, ask the vendors, or check the price of e-commerce, you can know the current price range.
