What are the synthesis methods of 2-cyano-5-aminotrifluorotoluene?
The synthesis method of 2-% cyano-5-nitrotrifluorotoluene has been explored by many predecessors in the ancient books, and it is described by you today.
One method can be started from compounds containing aromatic rings. First, halogenate the aromatic ring with a suitable halogenation reagent and introduce halogen atoms. The halogenation method requires selecting the appropriate reaction conditions, controlling the temperature, and selecting the solvent to make the reaction smooth. If a chlorinated reagent is used in a specific solvent, such as an aprotic solvent, heated to a suitable temperature, halogenated aromatics can be obtained.
Then, the halogenated aromatics react with cyanide reagents. This step is the key to introducing cyanide groups. Cyanide reagents, such as potassium cyanide and sodium cyanide, are commonly selected. With the help of phase transfer catalysts, the reaction can be carried out efficiently. Phase transfer catalysts can make better contact between the two-phase reactants and speed up the reaction rate. After the reaction is completed, the cyanide-containing intermediate is obtained by separation and purification.
Furthermore, the cyanide-containing intermediate is nitrified to introduce nitro groups. During nitrification, mixed acid (a mixture of nitric acid and sulfuric acid) is often used as a nitrifying agent. The ratio of mixed acid, reaction temperature and time need to be carefully controlled. If the temperature is too high, side reactions will occur; if the temperature is too low, the reaction rate will be slow. In this process, it is necessary to pay attention to the changes in the reaction system and operate with caution.
There is another method. The structure containing trifluoromethyl can be constructed first, and then cyano and nitro groups can be gradually introduced. Take an aromatic hydrocarbon containing active hydrogen as the starting material, and first react with trifluoromethylating reagents. There are many trifluoromethylating reagents, such as trifluoromethyl halides. After suitable reaction conditions, trifluoromethyl is connected to the aromatic ring.
Then, as the above method, cyano and nitro are introduced one after another. After the introduction of cyanyl groups, it has an impact on the distribution of electron clouds in molecules. When nitrification is carried out, the localization and reactivity of nitro groups also change. Therefore, each step needs to be carefully considered, and the reaction conditions should be adjusted in a timely manner according to the reaction mechanism and experimental results.
Although there are rules to follow in the synthesis process, the actual operation often encounters variables. The yield of each reaction step, the control of side reactions, and the separation and purification of products are all challenges. Experimenters need to have solid chemical foundation, rich practical experience, careful observation and careful choice in the reaction process, in order to synthesize 2-% cyano-5-nitrotrifluorotoluene and achieve the desired goal.
