(2-chloro-5-iodophenyl)(4-fluorophenyl)methanone

(2-Chloro-5-iodophenyl) (4-fluorophenyl) methyl ketone, an organic compound. Looking at its structure, it contains chlorine, iodine, fluorine and other halogen atoms, and the phenyl group is connected to the methyl ketone group. This structural feature makes it have unique chemical properties. The introduction of
halogen atoms has a great impact on its reactivity. Chlorine and iodine atoms change the distribution of molecular electron clouds due to electronegativity and atomic radius differences. Chlorine atoms have strong electronegativity and have electron-absorbing induction effects, which can reduce the electron cloud density of the benzene ring, reduce the electrophilic substitution reactivity of the benzene ring, and the reaction check point tends to be meso. Although the iodine atom is slightly less electronegative, the atomic radius is large and the steric resistance is significant, which also affects the molecular reactivity and selectivity.
Furthermore, the fluorine atom is connected to another phenyl group, and its electronegativity is extremely strong, and the electron-absorbing effect is very huge. It not only affects the electron cloud density of the benzene ring where it is located, but also affects the polarity of the entire molecule, which in turn affects its physical properties, such as solubility.
In the methyl ketone group, the carbonyl group is polar, and the carbon-oxygen double bond electron cloud is biased towards the oxygen atom, which makes the carbonyl carbon partially positively charged and vulnerable to the attack of nucleophilic reagents. Many nucleophilic addition reactions can occur, such as reacting with nucleophilic reagents such as alcohol

The reaction temperature is about 80-120 ℃, and the reaction time is several hours. After the reaction, the product is purified by extraction, column chromatography and other means.
Third, use 2-chloro-5-iodoaniline as the starting material, first diazotize it, and then react with 4-fluoroacetophenone. First dissolve 2-chloro-5-iodoaniline in an appropriate amount of inorganic acid, and add sodium nitrite at low temperature for diazotization. After that, the diazonium salt solution is slowly added to the reaction system containing 4-fluoroacetophenone, and the reaction is carried out under specific conditions.
