1- (2-Cyano-4- (4-cyanobenzyl) benzyl) -1H-pyrazole is an organic compound with interesting chemical properties and potential uses in many fields.
In terms of stability, this compound contains cyano and pyrazole ring structures. Cyano is a strong electron-absorbing group, which can change the distribution of molecular electron clouds and enhance its stability. The pyrazole ring is aromatic, and the conjugate system endows the compound with certain thermodynamic stability. Under normal conditions, it can exist relatively stably and is not prone to spontaneous decomposition reactions.
When it comes to reactivity, cyano can participate in a variety of reactions. For example, in the presence of nucleophiles, the cyanyl carbon atoms are partially positively charged, vulnerable to attack by nucleophiles, and nucleophilic substitution reactions occur, such as with alcohols under basic conditions, which can generate nitrile derivatives. This reaction can be used to construct more complex organic structures. At the same time, the nitrogen atom on the pyrazole ring has a lone pair of electrons, which can participate in the reaction as a nucleophilic check point, and react with electrophilic reagents such as halogenated hydrocarbons to realize the functionalization of the pyrazole ring, providing a way for the synthesis of new compounds.
In addition, the benzyl moiety in this compound has a certain activity of the α-hydrogen atom. Under the action of appropriate oxidants, α-hydrogen can be oxidized to form corresponding carbonyl compounds, which enriches its reaction types and product diversity.
In terms of solubility, because the compound contains multiple aromatic rings and polar cyanyl groups, it should have good solubility in some polar organic solvents such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF), which is conducive to various chemical reactions in solution. In non-polar solvents such as n-hexane, the solubility may be poor.

To prepare 1- (2-cyano-4- (4-cyanobenzyl) benzyl) -1H-pyrazole, the method is as follows:
First take an appropriate starting material, such as an aromatic hydrocarbon with a specific substituent. Taking an aromatic hydrocarbon as an example, in a suitable reaction vessel, add an appropriate amount of catalyst, such as a metal catalyst, and add a specific ligand. This ligand works synergistically with the catalyst to enhance the selectivity and activity of the reaction. Subsequently, a cyanogen-containing reagent is added, and the nucleophilic substitution reaction is carried out under suitable temperature and pressure conditions. This reaction requires precise control of the reaction time. If the time is too short, the reaction will not be fully functional, and if it is too long, it will produce side reactions.
After the nucleophilic substitution reaction is completed, the obtained product is preliminarily separated and purified. The target product is separated from the reaction mixture by a method such as column chromatography with a suitable eluent.
Then, the construction of the pyrazole ring is carried out with this intermediate containing cyanide groups. In another reaction system, a specific nitrogen-containing reagent is added to promote the intracolecular cyclization reaction under basic conditions. During the reaction, pay attention to the subtle changes in temperature, because temperature has a great influence on the rate of cyclization reaction and the configuration of the product.
After the cyclization reaction is completed, the product is purified again. The method of recrystallization can be used to select an appropriate solvent to precipitate the target product in a pure crystal form. After many operations, carefully control the reaction conditions and parameters of each step, and finally obtain 1- (2-cyanogen-4- (4-cyanobenzyl) benzyl) -1H-pyrazole.

1 - (2 - cyanogen - 4 - (4 - cyanobenzyl) benzyl) -1H - pyrazole is a genus of pesticides. When using, many matters need to be paid attention to.
First, safety protection must be comprehensive. This medicine contains cyanide groups and its toxicity should not be underestimated. When applying the medicine, protective equipment is essential. Protective clothing, gloves, and masks should be worn neatly to prevent the medicine from contacting the skin and respiratory tract. If accidentally contaminated, rinse with plenty of water immediately and seek medical attention as soon as possible.
Second, precisely control the dosage of the medicine. According to the actual situation of pests and diseases and the growth stage of crops, strictly refer to the instructions to prepare the liquid medicine. If the dose is too small, it will be difficult to obtain the effect of prevention and control; if the dose is too large, one will waste the medicine, and the other may cause drug damage, damage the crops, and may also pollute the environment.
Third, pay attention to the timing of application. For different diseases and insect pests, the best control timing is different. Generally speaking, when pests are young and the disease is at the beginning stage, the effect is the most ideal. If you miss this time, the prevention and control difficulty will increase.
Fourth, avoid environmental pollution. During the application process, prevent the liquid from dripping and dripping. The remaining medicine and packaging should be properly disposed of and should not be discarded at will to avoid polluting the soil and water sources.
Fifth, pay attention to the interval period. In order to ensure the quality and safety of agricultural products, it is necessary to maintain a certain interval between the two applications, so that the crops have enough time to metabolize the agent and reduce the residue.
Sixth, do not mix with contraindicated pesticides. After some pesticides are mixed, they may reduce their efficacy or produce pesticides. Be sure to read the instructions carefully or consult a professional before mixing. Only by following the above precautions carefully can we effectively control pests and diseases, and ensure the safety of humans and animals and the ecological environment.
