What are the chemical properties of 2-Fluoro-benzeneethanamine?

2-Fluoro-phenethylamine, this is one of the organic compounds. Its chemical properties are specific, let me go into detail.

From the basic point of view, the molecule contains an amino group (-NH2O), and the nitrogen atom in the amino group has a lone pair of electrons, which is easy to combine with protons (H 🥰), so it is alkaline. In an acidic medium, it can react with acids to form corresponding salts. If it encounters hydrochloric acid, 2-fluoro-phenethylamine hydrochloride will be formed. The reaction is like "yin and yang". The nitrogen atom of the amino group accepts protons to form positively charged ammonium ions, which attract chlorine ions to form stable salts.

And its nucleophilicity cannot be ignored. The nitrogen atom of the amino group is a nucleophilic reagent because it has a lone pair of electrons. In many chemical reactions, it can attack the electrophilic reagents. For example, in the nucleophilic substitution reaction, if it encounters an electrophilic reagent such as a halogenated hydrocarbon, the lone pair of electrons of the nitrogen atom will approach the carbon atom connected to the halogenated hydrocarbon in the halogenated hydrocarbon, and the halogenated atom will leave with a pair of electrons, thus forming a new compound. This process is like "defeating rigidity with softness". The nucleophilic amino group relies on the force of the lone pair of electrons to break the original structure of the halogenated hydrocarbon and build a new chemical connection.
< br The amino groups in the compound can be oxidized, and different oxidants will cause different oxidation products to be formed. When a specific mild oxidant is used, the amino group may be oxidized to imino (= NH), just like the gradual change of things, the amino group is oxidized "baptized", and the structure is slightly changed; if a strong oxidant is used, the degree of oxidation may be deeper, and the structure and properties of the product will also change greatly.

In addition, although the fluorine atoms on the aromatic ring are relatively stable, under certain conditions, in the case of strong nucleophiles, and in extreme environments such as high temperature and high pressure, the fluorine atoms may also undergo substitution reactions. This situation is like "static and dynamic". Under the action of strong external forces, the seemingly stable fluorine atom will also leave its original position and be replaced by other groups, thus making the structure and properties of the whole molecule completely new.

In summary, 2-fluoro-phenethylamine has basic, nucleophilic and other chemical properties due to the existence of amino groups and fluorine atoms in the structure, and can undergo various chemical reactions under different conditions, showing a variety of chemical behaviors.

What are 2-Fluoro-benzeneethanamine synthesis methods?

The synthesis method of 2-fluorophenethylamine has been known for a long time, and this is a detailed description for you.

First, 2-fluorophenylacetic acid can be started from 2-fluorophenylacetic acid. First, 2-fluorophenylacetic acid is co-heated with dichlorosulfoxide to convert the carboxyl group into an acid chloride. This reaction needs to be carried out in a well-ventilated environment with careful temperature control, because dichlorosulfoxide is corrosive and volatile. The obtained acid chloride reacts with ammonia to form an amide. This step of the reaction conditions is relatively mild, and it can be heated at room temperature or slightly. Subsequently, the amide is treated with a strong reducing agent such as lithium aluminum hydride, and the carbonyl group of the amide is reduced to meth However, lithium aluminum hydride has strong reductive properties and flammability in contact with water, so the operation must be careful.

Second, 2-fluorobenzaldehyde is used as the starting material. First, it undergoes a condensation reaction with nitromethane to generate 2-fluoro-β-nitrostyrene. This reaction often requires alkali catalysis, such as piperidine and other organic bases, at appropriate temperature and time, good yields can be obtained. Then 2-fluoro-β-nitrostyrene is reduced, which can be reduced by hydrogen under the catalysis of metal catalysts such as palladium carbon, or by chemical reduction methods such as iron powder and hydrochloric acid. The nitro group is reduced to an amino group, and the target product 2-fluoro-phenethylamine is obtained. However, when using hydrogen reduction, the device needs to be airtight and pay attention to explosion protection; the post-treatment of chemical reduction method is slightly more complicated, and impurities such as iron salts need to be removed.

Third, 2-fluorobromobenzene is used as raw material. First react with magnesium to make Grignard's reagent. This process requires an anhydrous and oxygen-free environment to ensure the stability of Grignard's reagent. Grignard's reagent reacts with ethylene oxide to generate 2-fluoro-phenylethanol. Next, 2-fluoro-phenylethanol reacts with p-toluenesulfonyl chloride to convert the hydroxyl group into p-toluenesulfonate, which is a good leaving group. Finally, the reaction with sodium azide, and then reduced, such as lithium aluminum hydride or triphenylphosphine and water system reduction, 2-fluoro-phenethylamine can be obtained. However, sodium azide is toxic and explosive, and special attention must be paid to safety.

What is the market price of 2-Fluoro-benzeneethanamine?

2-Fluoro-phenethylamine, this is a compound in organic chemistry. Its market price often fluctuates due to many factors, and it is difficult to hide it.

First, purity is the key factor. If its purity is extremely high, almost perfect, and there are few impurities, the price of such high-purity 2-fluoro-phenethylamine should be high. Because its preparation process must be complicated, it requires exquisite technology and strict control to achieve this purity, so the price is high, or it can reach tens or even hundreds of yuan per gram.

Second, the market supply and demand situation also affects the price. If the market demand for 2-fluoro-phenethylamine surges at a certain time, but the supply is relatively insufficient, just like the situation of shortage of supply, the price will rise like spring shoots. On the contrary, if there is excess supply and little demand, the price will inevitably decline.

Third, the preparation cost also affects its price. From the procurement of raw materials to the equipment and energy required in the synthesis process, it is all a cost composition. If raw materials are scarce and difficult to find, or the synthesis process is complicated and consumes a lot of resources, the cost will be high, and the price will also rise.

Fourth, regional differences also affect the price. Prices will vary in different places due to differences in economic conditions, tax policies, logistics costs, etc. There may be a significant price difference between prosperous cities and remote places.

In short, the market price of 2-fluoro-phenethylamine is like a changing wind cloud, which is affected by many factors, and it is difficult to give an exact and fixed value. To know the exact price, you need to carefully check the current market conditions and consult relevant suppliers or professionals to obtain more accurate price information.
