1,3,5-Tri (trifluoromethyl) benzene is an organic compound. In its structure, there are three trifluoromethyl groups connected at the intermediate position above the benzene ring.
The physical properties of this compound are mostly liquid at room temperature, with a certain volatility. Looking at its appearance, or it is a colorless and transparent liquid, it has a special odor. Because its molecule contains many fluorine atoms, its density is higher than that of ordinary benzene compounds, and it has good chemical stability.
On chemical properties, trifluoromethyl has strong electron absorption, which reduces the electron cloud density of the benzene ring. Therefore, in the electrophilic substitution reaction, its activity is lower than that of benzene. Taking the nitration reaction as an example, benzene is easy to form nitrobenzene under the action of concentrated nitric acid and concentrated sulfuric acid; while the nitration reaction of 1,3,5-tris (trifluoromethyl) benzene requires more severe conditions, and the main product is the meso-substitution product. Due to the positioning effect of trifluoromethyl, the meso-electron cloud density of the benzene ring is relatively high.

However, in case of strong oxidizing agents, and under specific conditions, the benzene ring may be broken to form fluorine-containing carboxylic acids and other products. In the nucleophilic substitution reaction, due to the low electron cloud density of the benzene ring, such reactions are generally not easy to occur. However, if there are leavable groups attached to the benzene ring, under appropriate nucleophilic reagents and conditions, nucleophilic substitution may occur.
And because of its fluorine-containing properties, in the field of materials science, it can be used to prepare polymer materials with special properties, such as fluoropolymers, which often have excellent chemical resistance, heat resistance and low surface energy. In pharmaceutical chemistry, it can be used as a structural fragment of a lead compound, providing a basis for the development of drugs with special biological activities.

The synthesis of 1,3,5-tris (trifluoromethyl) benzene is an important topic in organic synthetic chemistry. To prepare this substance, there are several common methods as follows.
First, an electrophilic substitution reaction is carried out with a reagent containing trifluoromethyl with a benzene derivative. Suitable trifluoromethylation reagents, such as trifluoromethyl halide, can be used to react with benzene derivatives under the action of an appropriate catalyst. This catalyst is often Lewis acid, such as anhydrous aluminum trichloride. The reaction mechanism is that Lewis acid activates trifluoromethyl halide, making it an active intermediate, which then attacks the benzene ring and undergoes electrophilic substitution. Trifluoromethyl is introduced at a specific position in the benzene ring.
Second, the coupling reaction catalyzed by transition metals. Halogenated benzene derivatives can be coupled with metal-organic reagents containing trifluoromethyl groups under the action of transition metal catalysts such as palladium catalysts. In this process, the transition metal first forms a complex with halogenated benzene, and the connection between trifluoromethyl and benzene ring is achieved through the steps of oxidative addition, transmetallization and reduction elimination. Selecting the appropriate ligand is crucial to regulate the selectivity and activity of the reaction.
Or, it can be obtained from other aromatic compounds containing trifluoromethyl groups by conversion of functional groups. For example, trifluoromethyl aromatic compounds containing convertible functional groups are first prepared, and then the functional groups are gradually converted into the desired structure through reactions such as reduction, oxidation, and substitution, and finally 1,3,5-tris (trifluoromethyl) benzene is synthesized.
All synthesis methods have advantages and disadvantages. In practical application, it is necessary to comprehensively consider various factors such as the availability of raw materials, the difficulty of reaction conditions, yield and selectivity, and make a careful choice to achieve the best synthesis effect.
