What are the synthesis methods of 2-chloro-1-fluoro-4- (trifluoromethyl) benzene?
To prepare 2-bromo-1-pentene-4- (triamylmethyl) naphthalene, the following ancient methods can be used.
First, the naphthalene is used as the beginning, and the alkylation is first performed. Take the naphthalene and the appropriate triamylmethyl halide, and perform the Fu-gram alkylation reaction under the catalysis of Lewis acid such as aluminum trichloride. The active position of the naphthalene can be combined with the triamylmethyl halide to obtain 1- (triamylmethyl) naphthalene. This step requires attention to the reaction temperature and the amount of catalyst to prevent the formation of polyalkylation products.
Second, brominate the 1 - (triamylmethyl) naphthalene. Liquid bromine is used as the bromine source, and a small amount of iron powder is added to an appropriate solvent such as dichloromethane. The bromine atom will selectively replace the hydrogen at a specific position on the naphthalene ring to obtain 2-bromo-1- (triamylmethyl) naphthalene. During operation, the dropwise addition rate of bromine and the reaction temperature should be controlled to avoid the generation of polybrominates. After
, prepare 1-pentene-4-based fragments. Prepare with a suitable halogenated pentene, such as 4-chloro-1-pentene, by a metal-organic reagent such as Grignard's reagent. Take magnesium strips and 4-chloro-1-pentene in anhydrous ethyl ether to initiate a reaction to obtain 4-pentenyl magnesium chloride. At the end of
, a coupling reaction is carried out. 2-Bromo-1 - (triamylmethyl) naphthalene and 4-pentenyl magnesium chloride are reacted under appropriate reaction conditions, such as tetrahydrofuran as a solvent, at appropriate temperatures. The two are coupled to obtain the target product 2-bromo-1-pentene-4 - (triamylmethyl) naphthalene. After the reaction is completed, the pure product can be obtained by separation and purification methods, such as column chromatography. Throughout the process, the conditions of each step of the reaction are finely regulated to increase the yield and purity of the product.
What are the precautions for storing and transporting 2-chloro-1-fluoro-4- (trifluoromethyl) benzene?
For 2-% -1-oxy-4- (trioxy methyl) naphthalene, if it is not stored in the warehouse, please pay attention to the important things.
If it is not stored, the first priority will be determined. It is appropriate to use a place that is dry and well-connected, and a source of fire and heat, so that the flammability of this material is clear. If it is in a tidal environment, or a place that causes problems, it will be like a situation. Moreover, oxidizing materials, acids and other substances should be stored separately. Because of their chemical activity, they will meet each other, and they may react violently and become large.
Furthermore, the storage container should not be ignored. It must be used in a container that is used and dense to prevent the object from being exposed. The material of the container should be able to withstand the corrosion of this object, and it should not be transformed and reversed, so as to preserve the preservation.
If it is not necessary, it must comply with the relevant regulations. People must be subject to, familiar with the characteristics of this object and the way to deal with it urgently. Therefore, 2-% -1-oxygen-4- (trioxy methyl) naphthalene should be carefully treated in order to ensure safety.
