What are the chemical properties of 4-chlorobenzene-1,2-diol?
4-Chlorobenzene-1,2-diol is 4-chloro-catechol, and its chemical properties are as follows:
This substance has phenolic commonality. The phenolic hydroxyl group is weakly acidic and can react with bases. If it encounters sodium hydroxide solution, the hydrogen in the phenolic hydroxyl group can be replaced by sodium ions to form sodium phenol and water. This reaction is a genus of acid-base neutralization. Its acidity is weaker than that of carbonic acid, so carbon dioxide is added to its sodium salt solution, and the phenol can be replaced.
The phenyl ring of 4-chloro-catechol is affected by the phenolic hydroxyl group, and the electron cloud density increases, making it more prone to electrophilic substitution. In the halogenation reaction, electrophilic reagents such as chlorine atoms are easy to attack the ortho and para-positions of the hydroxyl groups on the benzene ring. Because the two phenolic hydroxyl groups are in the ortho-position and interact with each other, the activity of the benzene ring is quite high. During halogenation, even without the need for a catalyst, it can quickly replace with halogens, introducing more halogen atoms on the benzene ring.
It is also easy to be oxidized. The electron cloud density of the carbon atoms connected to the phenolic hydroxyl groups is high, and it is easily oxidized under the action of oxygen or other oxidants in the air, resulting in the conversion of the phenolic hydroxyl group into a quinone structure, which often appears to be darker in color.
In the nucleophilic substitution reaction, In the presence of suitable nucleophiles such as sodium alcohol and amine, chlorine atoms can be replaced by corresponding groups to generate new organic compounds. This reaction is very important in organic synthesis and can be used to construct diverse organic molecular structures.

What are the synthesis methods of 4-chlorobenzene-1,2-diol?
4-Chlorobenzene-1,2-diol, also known as 4-chloro-catechol, has many exquisite synthesis methods. The following is the detailed description of Jun.
First, catechol is used as the starting material and can be prepared by halogenation reaction. This process requires the selection of suitable halogenating reagents, such as sulfoxide chloride, phosphorus oxychloride, etc. Taking sulfoxide chloride as an example, the catechol is dissolved in a suitable organic solvent, such as dichloromethane and chloroform, and the sulfoxide chloride is slowly added dropwise at low temperature. Because the activity of sulfoxide chloride is quite high, the reaction is easy to occur quickly, so the temperature needs to be carefully controlled to prevent side reactions. Add it dropwise, heat it up to a suitable temperature, and stir the reaction for several times. After the reaction is completed, the pure 4-chlorobenzene-1,2-diol can be obtained by reduced pressure distillation, column chromatography and other methods.
Second, 4-chlorophenol can also be synthesized from 4-chlorophenol. First, 4-chlorophenol is reacted with strong oxidants such as potassium permanganate and potassium dichromate under basic conditions to oxidize the phenolic hydroxyl group to a quinone structure. After the reduction step, the quinone structure can be reduced to the o-catechol structure by using reducing agents such as sodium borohydride and zinc powder, which is 4-chlorobenzene-1,2-diol. However, in this process, the condition control of the oxidation and reduction steps is crucial. Excessive oxidation can easily cause the destruction of the benzene ring; if the reduction is insufficient, the product is impure.
Third, halogenated aromatics are used as raw materials through metal-catalyzed coupling reactions, such as the Ullmann reaction. Halogenated aromatics and catechol are catalyzed by copper salts in an alkaline environment and high temperature conditions. This reaction requires the selection of suitable copper salts, such as cuprous iodide, etc., and ligands to promote the reaction. Although the Ullmann reaction conditions are harsh, high temperature and long reaction time are required, it is an effective synthesis route for specific substrates.
Fourth, m-chloroaniline is used as the starting material, and can also be prepared by diazotization and hydrolysis. First, m-chloroaniline is made into a diazonium salt. Generally, m-chloroaniline is treated with sodium nitrite and hydrochloric acid at low temperature to obtain a diazonium salt solution. After the diazonium salt solution is dropped into hot dilute sulfuric acid for hydrolysis, the diazonium group is replaced by the hydroxyl group to form 4-chlorobenzene-1,2-diol. During this process, the diazotization reaction needs to be strictly controlled at low temperature to prevent the decomposition of diazonium salts, and the hydrolysis step also needs to pay attention to the temperature and reaction time.

What are the chemical properties of 4-chlorobenzene-1,2-diol?
4-Chlorobenzene-1,2-diol is 4-chloro-catechol. This substance has the following chemical properties:
It contains phenolic hydroxyl groups and is weakly acidic. Due to the presence of phenolic hydroxyl groups on the phenolic ring, the oxygen atoms of the phenolic hydroxyl group form p-π conjugate with the phenolic ring, so that the oxygen-hydrogen bond electron cloud is biased towards the oxygen atom, and hydrogen is more easily dissociated. It can react with bases such as sodium hydroxide to form phenolates and water.
The phenolic hydroxyl groups of 4-chloro-catechol are easily oxidized. Oxygen in the air can slowly oxidize it. In case of strong oxidants such as potassium permanganate, under suitable conditions, the phenolic hydroxyl groups will be oxidized to quinones and other products, causing color changes, such as turning brown
Because the phenyl ring has a conjugated system, it has certain stability and electrophilic substitution reaction activity. The phenolic hydroxyl group in 4-chloro-catechol is an ortho-and para-localization group, which increases the electron cloud density of the phenyl ring ortho-and para-site, and is more prone to electrophilic substitution. If reacted with bromine water, bromine atoms will replace phenolic hydroxyl ortho-and para-hydrogen atoms on the phenyl ring to form bromogenic products.
4-chloro-catechol contains chlorine atoms. Although it is affected by the benzene ring, its activity is different from that of chlorine atoms in halogenated alkanes. However, under certain conditions, such as under specific reaction conditions such as strong bases and high temperatures, chlorine atoms can undergo substitution reactions and be replaced by other groups such as hydroxyl groups and amino groups to form new

4-Chlorobenzene-1,2-diol is 4-chlorobenzene, and its physical properties are as follows:
This substance is mostly solid at room temperature, and it usually appears white to light yellow crystalline. The change of this color state may be due to the impurities contained. It has a certain melting point, about 96-99 ° C. When heated to this temperature, it gradually melts from solid to liquid. The temperature of this phase transition is one of the important physical parameters to identify this substance.
4-chlorobenzene has a certain solubility in water, but the solubility is not high, and it is slightly soluble in water. Its solubility may be different in organic solvents. Organic solvents such as ethanol and ether have high affinity with them and can better dissolve 4-chloro-catechol. The difference in solubility is due to the fact that its molecular structure contains both hydrophilic hydroxyl groups and hydrophobic chloro-phenyl groups, so it shows different solubility characteristics in different solvents.
Its density is also an important physical property. Although there is no constant recorded in accurate ancient books, it can be known that its density is slightly larger than that of water, so it is left standing in water, or has a sinking state.
4-chloro-catechol is relatively stable at room temperature and pressure. In case of extreme conditions such as high temperature and open flame, or a chemical reaction occurs, there is a risk of combustion. And because it contains phenolic hydroxyl, easy to be oxidized, in the air for a long time, or due to oxidation and gradual change of color state, which is determined by its physical and chemical nature, with this material, must be observed.
