5-fluoro-2-iodoacetophenone

5-Fluoro-2-iodoacetophenone is a kind of organic compound. In terms of physical properties, it is mostly liquid at room temperature, with specific boiling point and melting point. However, due to the limitation of data, the exact values of these two are difficult to know. Looking at its appearance, it may be a colorless to light yellow transparent liquid with a special odor.
On its chemical properties, due to the presence of fluorine atoms, iodine atoms and carbonyl groups in the molecule, the chemical activity is very strong. The high electronegativity of fluorine atoms changes the electron cloud density of the benzene ring, which in turn affects the electrophilic substitution reaction activity of the benzene ring, and the reaction check point and rate change. Although the iodine atom is large in size, it is also a good leaving group. In the nucleophilic substitution reaction, the iodine atom is easy to leave and be replaced by other nucleophilic reagents. Carbonyl, as a typical functional group, can undergo many reactions, such as addition reaction with nucleophilic reagents. Common nucleophilic reagents such as alcohols and amines can react with them to form new compounds. When reacted with alcohols in acidic catalysts, ketals or semiketals can be formed; when reacted with amines, imines can be formed. In addition, 5-fluoro-2-iodoacetophenone may also participate in redox reactions. Carbonyl can be reduced to alcohol hydroxyl groups, and iodine atoms can also undergo oxidation reactions under specific conditions to convert into high-valent iodine compounds. In the field of organic synthesis, this compound is often used as an important intermediate to build more complex organic molecules through various chemical reactions, providing key starting materials for research and production in many fields such as medicinal chemistry and materials science.

There are three common methods for the synthesis of 5-fluorobenzene-2-iodoacetophenone. First, fluorobenzene is used as the starting material. Shilling fluorobenzene and acetyl chloride are acylated by Fu-g, and aluminum trichloride is used as the catalyst. In this reaction, the benzene ring of fluorobenzene is nucleophilic, and the carbonyl carbon of acetyl chloride is electrophilic. The two combine to synthesize 2-fluorobenzene. Then, 2-fluoroacetophenone is co-reacted with iodine and appropriate oxidants (such as hydrogen peroxide or nitric acid), and iodine replaces the ortho-hydrogen atom on the benzene ring to obtain 5-fluoro-2-iodoacetophenone. Due to the relatively high electron cloud density of fluorine, iodine tends to replace ortho-hydrogen.
Second, 2-iodoacetophenone is used as the starting material. Using nucleophilic substitution reaction, fluorine-containing reagents (such as potassium fluoride) are reacted with 2-iodoacetophenone. The reaction needs to be carried out in a polar aprotic solvent (such as dimethyl sulfoxide) at high temperature and in the presence of a phase transfer catalyst (such as tetrabutylammonium bromide). Fluoride ions act as nucleophiles to replace iodine atoms on the benzene ring, so as to obtain the target product 5-fluoro-2-iodoacetophenone.
Third, acetophenone is used as the starting material. First, through a halogenation reaction, acetophenone is reacted with iodine under appropriate conditions to generate 2-iodoacetophenone. Next, 2-iodoacetophenone is fluorinated. An electrochemical fluorination method can be used to generate 5-fluoro-2-iodoacetophenone in a specific electrolytic cell with a suitable electrode material and electrolyte under a certain current and voltage. This process involves electron transfer and chemical reaction on the electrode surface, and the operation needs to be carefully controlled.

5-Fluoro-2-iodoacetophenone is also an important agent in organic synthesis. In the field of medicinal chemistry, its work is very great. Due to its unique structure, it can be used as a key intermediate to produce various bioactive compounds. For example, the development of new antimalarial drugs, or the introduction of specific functional groups can be used to increase the affinity of the drug with the target of malaria parasites and improve the curative effect.
In the field of materials science, it also has its uses. With this as a raw material, after a specific reaction, materials with special optical or electrical properties can be prepared. For example, the synthesis of photoelectric conversion materials can help solar cells improve the photoelectric conversion efficiency, which is of great significance for the development of new energy.
In pesticide chemistry, 5-fluoro-2-iodoacetophenone can be used to create new insecticides or fungicides. By ingeniously designing reactions, it is constructed into the molecular structure of pesticides, giving pesticides a unique mechanism of action, or it can deal with the resistance problem of pests and pathogens, and ensure agricultural harvest.

5-Fluoro-2-iodoacetophenone, this product is in the market, and its price is difficult to determine. The change in its price depends on many reasons.
First, the quantity is the main reason. If the amount of purchase is huge, the merchant may give a discount to promote the transaction, and the price may be lowered; if the quantity is small, the merchant's profit is thin, and the price must be high.
Both, the source is related to the quality. From different places, the production method and raw materials are different, and the quality is also different. The superior material is pure and refined, and the price is high; the second, the price is low.
The three, the supply and demand of the market, determine the price. In addition, market competition, exchange rate movements, transportation costs, etc., can cause changes in price. The market is volatile today. The price of 5-fluoro-2-iodoacetophenone ranges from a few yuan to tens of yuan per gram or a few yuan per gram. It is difficult to determine the exact value. To know the detailed price, it is advisable to consult the chemical raw material supplier, or check it on the chemical trading platform, to get a near-real price.

5-Fluoro-2-iodoacetophenone is one of the organic compounds. Its physical properties are worth exploring.
