To prepare 2-cyano3-alkenyl butyric acid, the method is as follows:
can be obtained by a nucleophilic substitution reaction between a suitable alkenyl-containing compound and a cyanyl-containing reagent. For example, if the alkenyl compound has a suitable leaving group, such as a halogen atom, the cyano negative ion can attack the alkenyl compound and replace it, thereby introducing a cyano group. This is one of the common pathways.
Or by the conversion of carbonyl compounds. Starting from the alkenyl aldehyde or ketone, the addition reaction with the cyanyl group reagent, such as the addition of hydrocyanic acid, can obtain the alcohol compound containing the cyanide group, and then through suitable oxidation and other functional group conversion steps, the target 2-cyano3-alkenyl butyric acid can be prepared.
Furthermore, the reaction involving organometallic reagents can be used. For example, the Grignard reagent is made of alkenyl halide and metal magnesium, and then reacts with the cyanyl compound to introduce the cyanyl group, and then the structure of butyric acid is constructed through a series of reactions, and the final product is obtained.
During the synthesis process, attention should be paid to the control of reaction conditions, such as temperature, pH, etc. Too high or too low temperature may affect the reaction rate and selectivity; pH will also affect the stability and reaction path of the reaction intermediate. And each step of the reaction needs to consider the yield and purity, and select suitable reaction solvents and catalysts to ensure the efficient and smooth progress of the reaction, so as to successfully prepare 2-cyano3-alkenylbutyric acid.

The physical properties of 2-%-3-carboxylic acids are as follows: if it is not the same, it is the reaction of other substances, and the amount of the compound is also low. Under normal conditions, this compound or liquid is easy to form water molecules because of its alkyl group and carboxyl group, resulting in good solubility in water.
Its melting and boiling properties are high due to the action of molecules. The alkyl group can be poly-reactive, weakly acidic, and can be reactive to form a phase. Carboxylic acidic groups can also neutralize and react to produce carboxylic acid water.
This compound may have chemical properties. Due to the poor atomic properties in the molecule, the molecular composition of the molecules is uneven. The chemical properties make it soluble in water, such as alcohols, ketones, etc. Furthermore, its chemical activity is high, and the alkyl group and carboxyl group are all active groups. It can be esterified, substituted, and other reactions.
If there is a catalyst, the alkyl group can be oxidized to an aldehyde group or a carboxyl group, and the carboxyl group can also be formed. And the action of the molecule makes it under aggregation or a special arrangement, such as viscosity and surface force. Its density may be slightly higher than that of water, because there are other atoms in the molecule to increase its weight, and the molecular arrangement or water is denser.

The storage of 2-% -3-deuterium to its-4-boronic acid requires attention to the following general things:
First, it is necessary to pay attention to the temperature of the environment. Boric acid should be stored in a cool place. If the temperature is high, or it may cause its chemical properties to decrease, such as accelerating the process of decomposition, causing its weight to be reduced, the method should be used as usual. Generally speaking, with a temperature of 20 degrees Celsius, it is best not to make the temperature exceed 30 degrees Celsius, or it may be unexpected.
Second, the temperature of the environment should not be ignored. Boric acid has the property of absorption. If it is high in temperature, it is easy to absorb water and cause it to deliquescence. The moisture of the solution, or change its physical shape, or affect its chemical properties, so that the original effect is large. Therefore, the degree of phase should be lower than 60% of the environment, and the packaging should be dense to prevent external invasion.
Third, it is necessary to avoid the connection of incompatible materials. Boric acid cannot be used in a room, because it can cause biochemical reactions, resulting in its own destruction and loss of original properties. In addition, oxidation is also required, because it may lead to oxidation reactions, which is the same as the quality of boric acid.
Fourth, the packaging material is very important. It is recommended to use corrosion-resistant materials, such as high-density polyethylene containers, which can effectively block the influence of external factors such as boric acid, and do not react with boric acid itself, so as to retain boric acid in the storage period, It can maintain its inherent characteristics when needed, and can achieve normal functions.

Today, there are 2-chloro-3-fluoropyridine-4-boronic acid. The price range of its market depends on many factors, and it is difficult to determine the exact value.
First look at the source of raw materials. To prepare 2-chloro-3-fluoropyridine-4-boronic acid, if the starting material required is convenient to obtain and sufficient supply, the price will be relatively easy; on the contrary, if the raw material is rare and difficult to find, and the collection or synthesis is not easy, the cost will rise, resulting in high product prices.
Second discussion on the synthesis process. To synthesize this compound, the process is divided into complicated and simple. If the method is exquisite and efficient, and the steps are concise, the energy consumption and side reactions are small, the cost is controllable, and the price may become reasonable; however, if the process is complicated, multiple steps are required, and the yield of each step is not high, or special reagents and conditions are required, the cost will increase greatly, and the price will also rise.
The situation of market supply and demand is also the key. If the market demand for this product is strong, but the supply is limited, the seller has the advantage, and the price will often rise; if the supply exceeds the demand and the competition is fierce, the merchant will sell its goods or reduce the price.
In addition, the scale of preparation also has an impact. Large-scale production, due to the scale effect, the unit cost may be reduced, and the price also has room to decline; small-scale production, the unit cost is higher, and the price is naturally expensive.
Overall, the market price of 2-chloro-3-fluoropyridine-4-boronic acid, or due to the above factors, fluctuates from a few yuan to several hundred yuan per gram. The specific price needs to be carefully investigated according to the current market situation.
