1h Pyrazole 4 Iodo 1 5 Dimethyl

1H-pyrazole, 4-chloro-1,5-dimethyl-is an organic compound. Its chemical properties are unique, let me tell you in detail.
Among this compound, the pyrazole ring has electron-rich properties. Because the pyrazole ring contains two adjacent nitrogen atoms, and the nitrogen atom has lone pair electrons, it can participate in the conjugation system, which increases the electron cloud density of the pyrazole ring. This property makes 1H-pyrazole, 4-chloro-1,5-dimethyl-easily react with electrophilic reagents.
Among the 4-position chlorine atoms, chlorine has strong electronegativity and is an electron-withdrawing group. Its presence changes the electron cloud density distribution of the pyrazole ring. During the electrophilic substitution reaction, the electron cloud density of the adjacent and para-position of the chlorine atom is relatively reduced, and the electron cloud density of the meta-position is relatively increased. Therefore, the electrophilic reagent is easy to attack the interposition of the chlorine atom. At the same time, the chlorine atom can undergo a substitution reaction, and under suitable conditions, it can be replaced by other nucleophiles. For example, in the reaction with sodium alcohol, the chlorine atom can be replaced by alkoxy groups to form corresponding ether compounds.
Furthermore, the two methyl groups at the 1,5-position, with methyl as the power supply group, will increase the electron cloud density of the pyrazole ring, which has an activation effect on the electrophilic substitution reaction and makes the reaction easier to proceed. And methyl groups can enhance the lipid solubility
Under basic conditions, the hydrogen atom on the 1H-pyrazole, 4-chloro-1,5-dimethyl-pyrazole ring can be taken away by the base to form the corresponding negative ion. As a nucleophilic reagent, this negative ion can react with electrophilic reagents such as halogenated hydrocarbons to realize the functionalization of the pyrazole ring.

The common synthesis methods of 1H-pyrazole, 4-chloro-1,5-dimethyl-are as follows:
To prepare this product, a common method is to react with a compound containing pyrazole structure with a suitable halogenated hydrocarbon. First take halogenated hydrocarbons, such as chlorinated compounds, which need to have specific substituents. In a suitable organic solvent, such as dichloromethane, N, N-dimethylformamide, etc., add alkali substances, such as potassium carbonate, sodium carbonate, etc. The base can promote the reaction and enhance the activity of halogenated hydrocarbons. At the same time, the raw materials containing pyrazole structure and corresponding substituent vacancies at 4 and 5 positions are put into the system, heated and stirred, and maintained at a certain temperature. According to the reaction process and the properties of the raw materials, the temperature may vary from 50 to 100 ° C. After several hours, the substituents of halogenated hydrocarbons will undergo nucleophilic substitution reaction with the pyrazole structure, and the target products 1H-pyrazole, 4-chloro-1,5-dimethyl- are gradually formed.
Another method starts with the construction of pyrazole rings. Appropriate raw materials containing nitrogen and carbon, such as nitriles and hydrazines, are selected to form pyrazole rings through cyclization under acid or base catalysis. For example, under the action of acidic catalysts such as p-toluenesulfonic acid, specific nitriles and hydrazines are heated and refluxed in a suitable solvent to form a pyrazole ring parent. Then, for the 4th and 5th positions, the modification is carried out to introduce chlorine atoms and dimethyl groups. The introduced chlorine atoms can be chlorinated by chlorinated reagents, such as thionyl chloride, phosphorus oxychloride, etc., under suitable conditions; the introduction of dimethyl can use halogenated methane and alkali to complete the methylation reaction in a suitable reaction system to obtain the target product. All reactions require attention to the precise control of the reaction conditions, the purity of the raw materials and the monitoring of the reaction process, in order to improve the yield and purity of the product.
