What are the common synthesis methods for 2,3,6-trifluorobenzyl bromide?

The common synthesis methods of 2% 2C3% 2C6-trifluorobenzyl ether probably include the following.

First, the halogenated benzyl is reacted with trifluoroalcohol in an alkaline environment. For example, the halogenated benzyl, such as chlorobenzyl and bromobenzyl, is selected to react with trifluoroethanol under the catalysis of alkali, and the base can often be potassium carbonate, sodium hydroxide, etc. At a suitable reaction temperature and time, the halogen atom of the halogenated benzyl undergoes a nucleophilic substitution reaction with the hydroxyl group of the trifluoroethanol, and the halogen leaves to form 2% 2C3% 2C6-trifluorobenzyl ether. The reaction conditions are relatively mild and the operation is relatively simple. However, it is necessary to pay attention to the regulation of the ratio of reactants and the reaction conditions to improve the yield and purity of the product.

Second, the benzyl alcohol derivative reacts with the trifluorohalogenated hydrocarbon. After appropriate derivatization of benzyl alcohol, such as methanesulfonate or p-toluenesulfonate, the leaving group with higher activity such as benzyl alcohol is made, and then nucleophilic substitution occurs with trifluorohalogenated hydrocarbons such as trifluorobromomethane under the action of basic reagents. In this process, the basic reagent captures the hydrogen on the oxygen atom of the benzyl alcohol derivative to form an oxygen anion, initiates a nucleophilic attack on the carbon atom of the trifluorohalogenated hydrocarbon, and the halogen atom leaves, resulting in the final target product 2% 2C3% 2C6-trifluorobenzyl ether. This approach requires the derivatization of benzyl alcohol, which is slightly complicated, but it can effectively improve the selectivity and yield of the reaction under specific circumstances.

Third, the coupling reaction catalyzed by transition metals. For example, using transition metal catalysts such as palladium and copper to cross-couple benzyl-containing halides or borates with trifluoromethyl-containing halides or borates. This method usually requires specific ligands to stabilize the metal catalyst and promote the reaction. The coupling reaction conditions of transition metal catalysis are relatively mild, which can achieve some reactions that are difficult to achieve by traditional methods, and the selectivity of substrates is high, which can effectively synthesize complex structures of 2% 2C3% 2C6-trifluorobenzyl ether. However, this method has high catalyst cost, complex reaction system, and high requirements for reaction equipment and operation.
