What is the synthesis method of 1-Fluoro-4- [ (4-Fluorophenyl) Sulfonyl] Benzene
The synthesis method of 1-fluoro-4- [ (4-fluorophenyl) sulfonyl] benzene is a key problem in organic synthetic chemistry. To make this substance, the following path is often followed.
First, fluorobenzene derivatives are used as starting materials. You can first take 4-fluoro-thiophenol and the like, and then oxidize it to convert sulfur atoms into sulfonyl groups. The oxidizing agent can choose hydrogen peroxide oxidant in a suitable solvent, such as glacial acetic acid, to control the temperature. This process requires attention to the reaction temperature and time. If the temperature is too high, it may cause side reactions to multiply and lead to impure products; if the time is too short, the reaction will not be completed and the yield will not be high.
Second, 4-fluorobenzenesulfonyl chloride and 4-fluorophenylboronic acid can also be used as raw materials. The coupling reaction catalyzed by palladium realizes the connection between the two. Palladium catalysts are commonly used in tetra- (triphenylphosphine) palladium, and the choice of ligands is also related to the reaction effect. Ligands such as bipyridine can increase the reactivity. In the reaction system, the choice of base is also very important. Potassium carbonate, sodium carbonate, etc. are commonly used bases. In this reaction, the solvent can be selected from dichloromethane, toluene, etc., and under the protection of inert gas, heat and stir to make the reaction fully proceed.
Furthermore, if 4-fluoroaniline is used as the starting material, the diazonium salt can be prepared by diazotization reaction, and then reacted with fluorothiophenol to form thioether, and then oxidized to obtain the target product. The diazotization reaction requires a low temperature and acidic environment, using sodium nitrite as the reagent to obtain the diazonium salt, and then quickly reacts with thiophenol. The oxidation step follows the method described above to oxidize the thioether to a sulfonyl group.
The methods for synthesizing 1-fluoro-4- [ (4-fluorophenyl) sulfonyl] benzene are diverse, and each method has its advantages and disadvantages. In actual operation, it is necessary to weigh and choose according to the availability of raw materials, the difficulty of controlling reaction conditions, the purity and yield of the product, etc., in order to achieve the ideal synthetic effect.
What is the price range of 1-Fluoro-4- [ (4-Fluorophenyl) Sulfonyl] Benzene in the market?
In today's world, business conditions are ever-changing, and the price of goods also changes accordingly. 1 - Fluoro - 4 - [ (4 - Fluorophenyl) Sulfonyl] Benzene This item is in the market, and its price involves many factors, which are difficult to hide in a single word.
First, the difficulty of its production is related to the price. If the need to make it is very refined, the material is very precious, and the work is complicated and difficult, the price will be high; on the contrary, if the system is easy, the material is often simple, and the price may be slightly lower.
Second, the supply and demand of the market are also heavy. Those who want it are numerous, and those who supply it are few, the price will rise; if the supply exceeds the demand, the price will be self-suppressing.
There are also differences in origin and time, and the price is also different. When the freight increases from a distance, the price may be higher; when there are many goods in the place, the price may drop.
However, it is not easy to determine the range of its price. It is difficult to determine the level of its price because it has not carefully observed the changes and conditions of the market. Generally speaking, if it is an ordinary city, its price may be between [X1] gold and [X2] gold due to its nature and use. However, this is only speculation, not an exact number. The market situation is impermanent, and you must personally observe the business situation and consult the people of Jia before you can get its near-real price.
