What are the chemical properties of 1-chloro-4- (methylsulphonyl) -2-nitrobenzene
1 - chloro - 4 - (methylsulphonyl) - 2 - nitrobenzene, which is an organic compound containing chlorine, methyl sulfonyl group and nitro group on the benzene ring. Its unique chemical properties are a subject worthy of further investigation.
First talk about its halogenated hydrocarbon properties. The chlorine atom is attached to the benzene ring, giving this compound a certain activity. In case of nucleophiles, chlorine atoms may be substituted. For example, when meeting nucleophiles such as sodium alcohol, chlorine atoms may be replaced by alkoxy groups to form corresponding ether compounds. This substitution reaction requires suitable reaction conditions, such as appropriate solvents, temperatures and catalysts, to occur smoothly.
Furthermore, the methylsulfonyl group also has an important influence. This group has strong electron absorption, which can reduce the electron cloud density of the benzene ring and reduce the electrophilic substitution reactivity of the benzene ring. However, under certain conditions, electrophilic substitution can still occur on the benzene ring, but the reaction check point may be limited by the positioning effect of the methylsulfonyl group. Generally speaking, it is a meta-position group that guides electrophilic reagents to attack the benzene ring meta-position.
As for the nitro group, it is also a strong electron-absorbing group. It not only reduces the electron cloud density of the benzene ring, but also strengthens the polarity of the molecule. The presence of nitro groups changes the chemical stability of this compound. At the same time, under reduction conditions, nitro groups can be reduced to amino groups, and a series of new compounds can be derived, opening up new paths for organic synthesis.
In addition, 1-chloro-4- (methylsulphonyl) -2-nitrobenzene may participate in many organic reactions, such as coupling reactions. Under suitable catalyst and reaction conditions, it can be coupled with other organic halides or compounds containing unsaturated bonds to form more complex organic molecular structures, which shows important application potential in the field of organic synthetic chemistry.

What is the common synthesis method of 1-chloro-4- (methylsulphonyl) -2-nitrobenzene?
1-Chloro-4- (methylsulfonyl) -2-nitrobenzene is a common compound in organic synthesis. The synthesis method follows the following paths.
First, p-toluenesulfonic acid is used as the starting material. First, p-toluenesulfonic acid is heated with mixed acid (mixture of sulfuric acid and nitric acid), and the nitrification reaction is carried out. The ratio of mixed acid and the reaction temperature are the key. The strong acidity and dehydration properties of sulfuric acid can promote nitric acid to produce nitroyl positive ion, which is the active species of nitrification reaction. Controlling the temperature in a suitable range, such as 50-60 ° C, allows the nitro group to be selectively introduced into the ortho position of the benzene ring to obtain 4-methyl-3-nitrobenzenesulfonic acid. Subsequently, this product is reacted with a chlorinating agent, such as phosphorus pentachloride or thionyl chloride. Phosphorus pentachloride can provide chlorine atoms and replace the sulfonic acid group to obtain 1-chloro-4-methyl-2-nitrobenzene. Finally, 1-chloro-4- (methylsulfonyl) -2-nitrobenzene can be obtained with a suitable oxidizing agent, such as m-chloroperoxybenzoic acid, and the oxidized methyl group is methylsulfonyl.
Second, take p-chlorotoluene as the starting material. First, p-chlorotoluene is co-heated with fuming nitric acid and concentrated sulfuric acid, and at a suitable temperature, such as 30-40 ° C, the nitro group is introduced into the benzene ring ortho-position to obtain 2-nitro-4-chlorotoluene. After that, this product is interacted with chlorosulfonic acid, which can convert methyl groups into methanesulfonyl groups, and finally obtain the target product 1-chloro-4 - (methanesulfonyl) - 2-nitrobenzene. At the time of
synthesis, the reaction conditions at each step, such as temperature, ratio of reactants, reaction time, and choice of catalyst, need to be finely regulated to obtain a product with higher yield and purity.
