What are the synthesis methods of 4- (Trifluoromethyl) Iodobenzene?
There are several common methods for synthesizing 4- (trifluoromethyl) iodobenzene.
One is to use benzene derivatives containing trifluoromethyl as the starting material and prepare it by halogenation reaction. For example, p-trifluoromethylaniline is used as the starting material and reacts with potassium iodide after diazotization. First, p-trifluoromethylaniline and sodium nitrite are diazotized in an acidic low temperature environment to form diazonium salts. This process requires strict temperature control to prevent the decomposition of diazonium salts. Then add potassium iodide solution, and the diazonium group is replaced by iodine, so 4 - (trifluoromethyl) iodobenzene is obtained. The advantage of this method is that the raw materials are relatively easy to obtain and the steps are relatively clear; however, the diazotization reaction requires low temperature operation, the conditions are more severe, and the sodium nitrite is dangerous, so the operation needs to be cautious.
The second can be reacted with trifluoromethylbenzene and iodine in the presence of an appropriate catalyst. The commonly used catalysts are copper salts, such as cuprous iodide. In this reaction system, trifluoromethylbenzene and iodine are catalyzed by cuprous iodide, the presence of ligands, and the action of appropriate bases to achieve the substitution of iodine for benzene cyclohydrogen. In this process, the ligand can enhance the activity and selectivity of the catalyst, and the base can help to promote the reaction. This method is relatively mild in operation and does not require high equipment; however, the cost of catalyst and ligand may be higher, and the reaction time may be longer.
Third, it is synthesized by Grignard reagent method. First, Grignard reagent containing trifluoromethyl is prepared, such as by reacting trifluoromethyl halogenated hydrocarbons with magnesium in anhydrous ether or tetrahydrofuran solvents. After that, the Grignard reagent reacts with iodine aromatic hydrocarbons or related halides and converts into 4- (trifluoromethyl) iodobenzene through a series of reactions. This method can achieve specific structure construction and is of great significance for complex molecular synthesis; however, the preparation of Grignard reagents requires an anhydrous and oxygen-free environment, which requires harsh conditions and high operation requirements.
