Therefore, it is necessary for people with deep cultivation and correct hearts to use it in order to achieve its wonders and use it in the world for the benefit of life. Otherwise, it is afraid that it will cause harm to others.
What are the synthesis methods of 3-fluoro-5-iodotrifluorotoluene?
The common methods for the synthesis of 3-bromo-5-iodine trifluorotoluene are as follows:
One is the halogenation reaction method. Appropriate aromatic compounds are used as starting materials, such as toluene derivatives. First, the trifluoromethylation reaction of toluene can be carried out by using suitable trifluoromethylation reagents, such as trifluoromethyl halide or trifluoromethylated metal reagents, etc., under appropriate catalysts and reaction conditions, trifluoromethyl is introduced into the toluene molecule to generate trifluorotoluene derivatives. Then, using brominating reagents, such as bromine ($Br_2 $), in the presence of catalysts such as iron powder or iron tribromide, the bromination reaction is carried out, and bromine atoms are introduced at specific positions in the benzene ring. Finally, iodizing reagents, such as iodine ($I_2 $), and suitable oxidation reagents and catalysts, such as hydrogen peroxide and copper salts, are used to introduce iodine atoms into the benzene ring to obtain 3-bromo-5-iodine trifluorotoluene. The steps of this method are relatively clear, but the reaction conditions of each step need to be precisely controlled to ensure the selectivity and yield of the reaction.
The second is the coupling method of metal-organic reagents. Select an aromatic halide containing trifluoromethyl and couple it with a metal-organic reagent containing bromine and iodine. For example, prepare a metal-organic reagent such as an aryl borate containing trifluoromethyl or an aryl reagent such as zinc, and prepare a halogenated aromatic hydrocarbon containing bromine and iodine at the same time. Then, under the action of transition metal catalysts such as palladium and nickel, the coupling reaction between the two occurs. Such reaction conditions are relatively mild and require high substrate selectivity. However, if appropriate ligands and reaction conditions are selected, high yields and selectivity can be obtained, and the target product 3-bromo-5-iodotrifluorotoluene can be effectively synthesized.
The third is the halogenation method guided by the guiding group. Introduce a directable group on the toluene derivative, such as the guide group of amino, hydroxyl and other derivatives. The guide group can guide the halogenation reaction to preferentially occur at a specific position of the benzene ring. First, bromine atoms are introduced at a specific position in the benzene ring under the guidance of a guide group by using a brominating reagent, and then the guide group is removed or properly converted. Then, iodine atoms are introduced by using a guide group again or using other strategies, and finally 3-bromo-5-iodotrifluorotoluene is prepared through a series of reactions and post-processing. The key to this method is the selection of the guide group and the removal or transformation of the guide group after the reaction, which can better control the halogenation position, but the steps are relatively complicated, and the reaction process needs to be carefully designed.
What should be paid attention to when storing and transporting 3-fluoro-5-iodotrifluorotoluene?
Three-five-and-three-and-five-and-three-and-five-and-three-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-three-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-three-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five-and-five It is made of solid materials to prevent it from being crushed by external forces on the way; it is wrapped in moisture-proof materials to prevent the intrusion of the outside world; it is wrapped in materials that are separated from the environment, so that it will not be harmed by the degree of damage.

It is also not allowed to be mixed with toxic and harmful things to prevent them from being stained and endangering the safety of users.
Fourth, the degree of control. The degree of concealment should be kept stable. The degree of resistance is high, or the composition is low, and the degree of resistance is low, and it is feared that it will be damaged. Generally speaking, it is appropriate to control the degree of resistance to a specific degree, depending on the characteristics of Sanjiazhi.
Fifth, check the secrecy. Whether it is hidden or hidden, it needs to be checked regularly. It has the appearance of being damp, damaged, and eaten.
