What are the chemical properties of Toluene, Alpha, alpha, alpha - trifluoro - o - iodo -
Toluene ，α,α,α - trifluoro-o-iodine (this substance may be inaccurate, speculated to be related substances such as o-iodine trifluoromethylbenzene), and its chemical properties are unique. This substance contains trifluoromethyl, which is highly electronegative due to the high electronegativity of fluorine atoms, causing trifluoromethyl to have strong electron absorption. This property reduces the density of the benzene ring electron cloud and weakens the activity of electrophilic substitution. Compared with ordinary toluene, electrophilic reagents are more difficult to attack, requiring more severe conditions and stronger electrophilic reagents.
However, due to its iodine atom, although the iodine atom decreases the density of the benzene ring electron cloud slightly, due to the conjugation effect, the In the electrophilic substitution reaction, the electrophilic reagent is more likely to attack the ortho and para-sites of the iodine atom. In addition, the iodine atom has a large atomic radius, and the steric resistance effect is obvious, which has a great influence on the selectivity of the reaction check point.
From the perspective of oxidation reaction, trifluoromethyl has high stability and is difficult to be oxidized by common oxidants. If there is a side chain on the benzene ring, such as a side chain similar to toluene, under the action of strong oxidants, the side chain may be oxidized to carboxyl groups, but due to the strong electron absorption of trifluoromethyl, the oxidation reaction conditions may be more severe.
In the halogenation reaction, because the electron cloud density of the benzene ring is affected by the trifluoromethyl group and the iodine atom, the halogenation reaction activity and check point selectivity are different from that of ordinary aromatic hydrocarbons. Electrophilic halogenation reagents tend to attack the ortho and para-sites of iodine atoms, and due to the reduction of benzene ring activity, the reaction rate may be slower than that of conventional aromatic hydrocarbon halogenation.
In the nucleophilic substitution reaction, due to the strong electron absorption of trifluoromethyl group, the electron cloud density of the benzene ring is reduced, which is conducive to the attack of nucleophilic reagents, and nucleophilic substitution reactions can occur. If

What is the preparation method of Toluene, Alpha, alpha, alpha - trifluoro - o - iodo -
The method of preparing α,α,α - trifluoro-o-iodotoluene, although the ancient book "Tiangong Kaiwu" does not describe the preparation method of this specific substance in detail, it can be deduced according to the idea of preparation of analogs and chemical principles.
To prepare this substance, toluene is often used as the starting material. The methyl group of toluene can be introduced into halogen atoms by halogenation reaction. Due to the need to prepare fluorides, suitable fluorination reagents can be selected, such as fluorinated metal salts or specific organic fluorine reagents.

Then, for the iodization of the ortho-position on the benzene ring, an iodine source and a suitable catalyst can be selected. Common iodine sources such as iodine elements, catalysts such as some metal salts or Lewis acids. In a specific reaction system, the electrophilic substitution reaction properties of the benzene ring are used to selectively replace the hydrogen atoms in the ortho-position of the iodine atom to obtain α,α,α - trifluoro-o-iodotoluene.
During the reaction process, it is necessary to pay attention to the precise control of the reaction conditions. If the temperature is too high, or the side reactions will increase and the yield will decrease; if the temperature is too low, the reaction rate will be slow and the time-consuming will be too long. And the purity and dosage ratio of each re After the reaction is completed, it needs to be separated and purified to obtain a high-purity target product.
