5-chloropyridine-3-carbonitrile

5-Chloropyridine-3-formonitrile is one of the organic compounds. Its chemical properties are unique, with nitrile groups (-CN) and chlorine atoms (-Cl) at specific positions in the pyridine ring.
nitrile groups have high chemical activity. When exposed to water, under suitable conditions, the corresponding carboxylic acid or amide can be hydrolyzed. If hydrolyzed in an acidic medium, after the intermediate amide, the final 5-chloropyridine-3-formic acid; if hydrolyzed in an alkaline medium, carboxylate can be obtained, and the acid can also be obtained after acidification. Nitrile groups can also participate in reduction reactions. If treated with suitable reducing agents, they can be converted into amine groups, which may generate 5-chloropyridine-3-methylamine derivatives.
Furthermore, chlorine atoms are also reactive check points. It can undergo nucleophilic substitution reactions, and chlorine atoms can be replaced when encountering nucleophiles. For example, when reacting with alkoxides, chlorine can be replaced by alkoxy groups; when reacting with amines, new nitrogen-containing derivatives can be formed. The pyridine ring itself is aromatic. Due to the presence of nitrogen atoms, the electron cloud distribution is uneven, which affects the reactivity of the substituents on the ring, making the electron cloud density of the adjacent and para-position relatively low, and the meta-position slightly higher, resulting in nucleophilic substitution reactions mostly occur in the adjacent and para-position of the carbon attached to the chlorine atom.

The synthesis method of 5-chloropyridine-3-formonitrile, although the ancient book "Tiangong Kaiwu" does not contain this material, in terms of today's chemical synthesis ideas, there are the following common ones.
First, pyridine is used as the starting material. The chlorination reaction of pyridine is carried out first, and under appropriate conditions, chlorine gas or chlorine-containing reagents can be used to introduce chlorine atoms into pyridine at the 5-position in the presence of suitable catalysts such as iron-based catalysts to obtain 5-chloropyridine. Then, 5-chloropyridine is cyanylated, for example, with cyanide reagents such as cuprous cyanide, under appropriate organic solvent and heating conditions, the cyanyl group is introduced at the 3-position of pyridine to obtain 5-chloropyridine-3-formonitrile.
Second, start from 3-cyanopyridine. Chlorination of 3-cyanopyridine is carried out under specific reaction conditions, such as light or the presence of free radical initiator, using suitable chlorination reagents, such as N-chlorosuccinimide (NCS), and chlorine atoms are selectively introduced at the 5-position to obtain the target product 5-chloropyridine-3-formonitrile.
Third, 5-chloro-3-halopyridine is used as the raw material, and the halogen atom can be bromine or iodine. The cyanide reagent, such as potassium cyanide or sodium cyanide, is used to carry out nucleophilic substitution reaction in the presence of phase transfer catalyst, and the halogen atom is replaced by cyanyl group to achieve the synthesis of 5-chloropyridine-3-formonitrile.

5-Chloropyridine-3-formonitrile is a commonly used raw material in organic synthesis. During storage and transportation, many matters must be paid attention to.
When storing, the first environment. It should be placed in a cool, dry and well-ventilated place. This is because the substance is afraid of moisture, and the humid environment is easy to cause its deterioration, damage its chemical properties, and then affect the effect of subsequent use. If the ambient humidity is too high, water vapor may react with 5-chloropyridine-3-formonitrile, or cause adverse phenomena such as hydrolysis.
Temperature is also crucial. Avoid high temperature, high temperature or thermal decomposition of the substance, or even cause safety accidents. And it should not be mixed with oxidizing agents, acids, alkalis and other substances. Due to its active chemical properties, contact with the above substances, or violent chemical reactions, may cause fire and explosion.
As for transportation, the packaging must be strong and sealed. This can prevent leakage during transportation. If it leaks, it will not only cause material loss, but also cause pollution to the environment and may endanger the safety of transportation personnel. During transportation, it is also necessary to maintain stability and avoid violent vibration and collision to prevent package damage. Transportation vehicles should also be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.
In addition, transportation and storage personnel should be familiar with the characteristics of 5-chloropyridine-3-formonitrile and emergency treatment methods. In the event of a leak, quickly isolate the leak area and restrict personnel from entering and leaving. Emergency personnel should wear appropriate protective equipment to avoid direct contact with the leak. According to the leakage situation, take reasonable collection and cleaning measures to ensure the safety of personnel and the environment.
