What is 2-Fluoro-Benzeneethanamine synthesis method?
The synthesis of 2-fluoro-phenethylamine is an important topic in the field of organic synthesis. There are many methods, and the common methods are described in detail below.
One is the nucleophilic substitution method for halogenated aromatic hydrocarbons. First, take 2-fluorobromobenzene, use it as the starting material, and take sodium cyanide in a suitable organic solvent such as N, N-dimethylformamide (DMF). Under the condition of heating and phase transfer catalyst, a nucleophilic substitution reaction occurs, and 2-fluorobenzene acetonitrile can be obtained. In this reaction, negative cyanide ions act as nucleophiles to attack the carbon atoms of halogenated aromatics, and the halogen atoms leave to form carbon-carbon bonds. Subsequently, 2-fluorophenylacetonitrile was catalyzed for hydrogenation and reduction. Palladium-carbon (Pd-C) was used as catalyst, hydrogen was used as reducing agent, and cyanyl was reduced to amino group in alcohol solvent, and finally 2-fluorophenylethylamine was obtained. This path step is relatively simple, but sodium cyanide is highly toxic. The operation must be cautious and well protected to prevent poisoning.
The second is the Grignard reagent method. Grignard reagent 2-fluorophenyl magnesium bromide was prepared by using 2-fluorobrobenzene and magnesium chips in anhydrous ether or tetrahydrofuran. Grignard reagent has high activity, reacts with ethylene oxide, ethylene oxide opens the ring, forms a carbon-carbon bond, and generates 2- (2-fluorophenyl) ethanol. Next, 2- (2-fluorophenyl) ethanol reacts with p-toluenesulfonyl chloride to convert the hydroxyl group into a p-toluenesulfonate ester group to enhance the ability to leave. Then reacts with sodium azide, and the azide group replaces the p-toluenesulfonate ester group to obtain 2- (2-fluorophenyl) ethyl azide. Finally, after reduction, such as reduction with triphenylphosphine, the azide group is converted into an amino group to obtain 2-fluoro-phenethylamine. Although there are many steps in this process, the reaction conditions of each step are mild and the yield is acceptable.
Another fluorination method using phenethylamine as raw material. Phenethylamine and suitable fluorination reagents, such as Selectfluor, introduce fluorine atoms at specific positions in the benzene ring in the presence of appropriate solvents and bases to obtain 2-fluoro-phenethylamine. This method directly fluoridates phenethylamine, and the steps are simple. However, the price of Selectfluor is high, and the cost restricts industrial production.
When synthesizing 2-fluoro-phenethylamine, the synthesis method should be carefully selected according to factors such as actual demand, raw material availability, cost consideration and operation safety, in order to achieve the synthesis goal of high efficiency, economy and safety.
What are the precautions in storage and transportation of 2-Fluoro-Benzeneethanamine?
2-Fluoro-phenethylamine is an organic compound. During storage and transportation, many key matters need to be paid attention to to ensure its stability and safety.
First, the storage temperature is very important. It should be stored in a cool and ventilated place, away from fire and heat sources. Because of its certain volatility and flammability, high temperature is prone to increased volatilization and increases the risk of fire. The temperature should usually be controlled at 2-8 ° C. This temperature range can effectively slow down the volatilization rate and chemical reaction process of the substance, and ensure its chemical stability.
Second, be sure to pay attention to sealed storage. 2-Fluoro-phenethylamine is easy to react with oxygen, moisture and other substances in the air, and poor sealing will cause it to deteriorate. It is necessary to use a suitable sealed container, such as a glass bottle or a metal drum, and ensure that the lid is tightly sealed to prevent air and moisture from invading.
Third, during transportation, avoid violent vibration and collision. The chemical structure of this substance contains benzene rings and amine groups. Violent vibration or collision may cause damage to the molecular structure, trigger chemical reactions, and even cause serious consequences such as explosions. Therefore, it is necessary to properly fix it during transportation, and choose a smooth transportation method to reduce the probability of vibration and collision.
Fourth, 2-fluoro-phenethylamine is a toxic and harmful substance. Operators and transportation personnel should be equipped with appropriate protective equipment, such as protective gloves, protective glasses and gas masks, to prevent direct contact or inhalation of the substance and ensure personal safety.
Fifth, storage and transportation sites need to have clear warning signs indicating the toxic, flammable and other characteristics of the substance to remind personnel to pay attention to safety. At the same time, the site should be equipped with corresponding fire and leakage emergency treatment equipment, such as fire extinguishers, adsorbents, etc., so that in the event of an emergency, rapid response measures can be taken to reduce hazards.
