What are the synthesis methods of 2,4,5-trifluorobenzyl cyanide?
To prepare 2,4,5-trifluorobenzoyl chloride, the method is as follows:
First, start with 2,4,5-trifluorobenzoic acid and heat it with sulfoxide chloride. The two are mixed, and at a suitable temperature, the oxygen of the thiophilic carboxyl group in the sulfoxide chloride is substituted, and the carboxyl group is transferred to the acyl chloride group to escape sulfur dioxide and hydrogen chloride. The reaction is simple and pure, and the post-treatment is easy. The sulfoxide chloride is often slightly excessive. After the reaction is completed, it is slightly steamed, and the rest is the product.
The second, 2,4,5-trifluorobenzoic acid reacts with phosphorus trichloride. The carboxyl group of benzoic acid interacts with phosphorus trichloride, and after complex transformation, the carboxyl group becomes the acyl chloride group, and the phosphorus becomes the phosphoric acid. This reaction condition is relatively slow, but when the product is separated, the separation of phosphoric acid and the product needs to be carefully operated.
Third, with 2,4,5-trifluorotoluene as the starting material, 2,4,5-trifluorobenzoic acid is first oxidized to obtain 2,4,5-trifluorobenzoic acid, and then the above-mentioned method of reacting with thionyl chloride or phosphorus trichloride is used to obtain the target substance. During oxidation, strong oxidants, such as potassium permanganate, are commonly used to make methyl transcarboxyl groups, and the subsequent acylation steps are the same as described above. Each method has its own advantages and disadvantages, and it needs to be used according to the actual situation, such as the availability of raw materials, the consideration of cost, and the purity of the product.
What are the precautions for 2,4,5-trifluorobenzyl cyanide in storage and transportation?
2% 2C4% 2C5-tribromobenzyl bromide is a commonly used reagent in organic synthesis. During storage and transportation, many matters need to be paid attention to, as detailed below.
First words for storage, this reagent is active, corrosive and irritating, so it should be placed in a cool, dry and well-ventilated place. Do not approach fire or heat sources to prevent them from being dangerous due to heat. Because it is sensitive to air and moisture, it should be sealed and stored to avoid contact with air and moisture and deterioration. Storage containers should also be carefully selected. Use corrosion-resistant materials, such as glass or specific plastic containers, and the containers must be tightly sealed.
As for transportation, it is necessary to act in accordance with relevant regulations on the transportation of hazardous chemicals. Before transportation, the packaging should be properly packed to ensure that there is no risk of leakage. The packaging material should be able to effectively buffer to prevent the container from being damaged due to collision during transportation. Transportation personnel must also undergo professional training and be familiar with the characteristics of this reagent and emergency disposal methods. During transportation, closely monitor environmental conditions such as temperature and humidity to avoid exposure to extreme environments. If there is an accident such as leakage during transportation, it should be dealt with immediately according to the emergency plan, evacuate the surrounding personnel, prevent the spread of pollution, and notify the relevant departments in time.
