The synthesis of 1-bromo-2,4-bis (trifluoromethyl) benzene is an important topic in the field of organic synthesis. There are many methods, and the common ones are described below.
Fluorinated aromatic compounds are used as starting materials, and the target product can be formed by halogenation reaction. For example, with 2,4-bis (trifluoromethyl) benzene as a substrate, bromine atoms can be introduced under appropriate halogenation reagents and reaction conditions. Commonly used halogenation reagents include N-bromosuccinimide (NBS), which is refluxed in an inert solvent such as carbon tetrachloride in the presence of an initiator such as benzoyl peroxide (BPO). This is a free radical substitution mechanism. Light or heat can decompose the initiator to produce free radicals, which can then initiate the substitution of bromine atoms to the benzene ring, resulting in 1-bromo-2,4-bis (trifluoromethyl) benzene.
Furthermore, halogenated aromatics can also be used as starting materials, and trifluoromethyl can be introduced through nucleophilic substitution reaction. Taking 1-bromo-2-chlorobenzene as an example, it is reacted with trifluoromethylating reagents such as trifluoromethyl copper lithium reagent (CF 🥰 CuLi) in a suitable solvent such as tetrahydrofuran under low temperature, anhydrous and oxygen-free conditions. The nucleophilic substitution reaction requires strict control of the reaction conditions, and an anhydrous and oxygen-free environment is essential, otherwise the reagent
In addition, the reaction path catalyzed by transition metals is also quite effective. Taking palladium catalysis as an example, the aryl halide is reacted with trifluoromethylated reagents under mild conditions by using suitable ligands. For example, 1-bromobenzene is used as the starting material, and trifluoromethylborate reagents are reacted with trifluoromethylborate reagents in the presence of palladium catalyst, specific ligands and bases. Such reaction conditions are relatively mild and good selectivity, which can effectively synthesize the target product, and the reaction effect can be optimized by adjusting the ligand and reaction conditions, and the yield and selectivity can be improved.
The synthesis of 1-bromo-2,4-bis (trifluoromethyl) benzene has various methods, each with advantages and disadvantages. The appropriate synthesis route should be carefully selected according to the actual situation, such as the availability of raw materials, the ease of control of reaction conditions, and the requirements of product purity.
