4 - (bromomethyl) -1 - chloro - 2 - (trifluoromethyl) benzene has been synthesized in ancient times, and there are many kinds. The following are several common methods:
First, halogenated aromatics are used as starting materials. Take appropriate halogenated aromatics, such as chlorine or bromine-containing benzene derivatives, and react with specific reagents. The nucleophilic substitution reaction is often necessary, and suitable nucleophilic reagents, such as bromomethyl-containing reagents, are selected. Under appropriate reaction conditions, such as in a specific solvent, a suitable catalyst is added, and the reaction temperature and time are controlled to prompt the nucleophilic reagent to attack the specific position of the halogenated aromatic hydrocarbon, and then bromomethyl is introduced, while retaining chlorine and trifluoromethyl, and the final product is obtained. For example, this nucleophilic substitution process can be achieved by stirring the reaction at a certain temperature in an organic solvent such as N, N-dimethylformamide (DMF) with potassium carbonate as a base.
Second, the reaction of arylboronic acid and its derivatives is assisted. Aryl boric acid or borate esters containing trifluoromethyl and chlorine are first prepared, and then they are coupled with halogenated hydrocarbons containing bromomethyl methyl under palladium catalysis. This reaction condition is very critical. The type of palladium catalyst, the choice of ligand, the type and amount of base, and the reaction solvent will all affect the efficiency and selectivity of the reaction. Generally speaking, in solvents such as dichloromethane or toluene, palladium acetate is used as the catalyst, bipyridine is used as the ligand, and cesium carbonate is used as the base. Under the condition of heating and refluxing, the target compound can be effectively synthesized.
Third, starting from the derivative of benzene, the target structure is constructed through multi-step reaction. First, a specific substituent is introduced to the benzene ring, such as by the Fourier-Gram reaction, which introduces chlorine atoms and trifluoromethyl into the benzene ring. Then, through suitable reaction steps, one of the positions is converted to bromomethyl. For example, trifluoromethyl is introduced by the Fu-gram alkylation reaction, then chlorine atoms are introduced by the halogenation reaction, and finally bromomethyl is introduced by the halomethylation reaction, such as in the presence of light or initiator, with brominating reagents and formaldehyde. After multiple carefully designed reactions, the synthesis of 4- (bromomethyl) - 1 - chloro - 2 - (trifluoromethyl) benzene is achieved.
