6-chloro-3-nitropyridine-2-carbonitrile

6-Chloro-3-nitropyridine-2-formonitrile, this is an organic compound. Looking at its structure, it contains chlorine atoms, nitro groups, cyano groups and pyridine rings, which give it unique chemical properties.
Let's talk about the chlorine atom first. It has electron-withdrawing properties, which can reduce the electron cloud density of the pyridine ring, weaken the electrophilic substitution reaction activity on the ring, but enhance the nucleophilic substitution reaction activity. For example, in case of nucleophilic reagents, the chlorine atom may be replaced and another compound may be derived. < Br >
Looking at the nitro group again, it is also a strong electron-absorbing group, which not only affects the electron cloud distribution of the pyridine ring, strengthens the electron-deficient characteristics of the ring, but also reduces the density of the electron cloud of the ortho and para-position more than that of the meso. In some reactions, the nitro group can be reduced and converted into other functional groups such as amino groups, which greatly expands the reaction path of the compound.
Cyanyl is of great significance in organic synthesis. It can not only hydrolyze to form carboxyl groups, but also reduce to amino methyl groups, or undergo addition reactions with many reagents, such as addition with Grignard reagents, to construct complex organic molecules.
The pyridine ring is the core of this compound, and its nitrogen atom imparts cyclic basicity. However, due to the electron-withdrawing effect of chlorine atoms and nitro groups, the basicity Under acidic conditions, pyridine cyclic nitrogen atoms or protons can affect the solubility and reactivity of compounds.

6-Chloro-3-nitropyridine-2-formonitrile is also an important intermediate in organic synthesis. There are many opinions on the synthesis method, and the number is short.
First, pyridine is used as the starting material. Before the appropriate position of pyridine, the cyano group can be introduced, and the nucleophilic substitution reaction can be carried out by halogenated pyridine and cyanide reagents, such as cuprous cyanide, under suitable reaction conditions to form pyridine-2-formonitrile derivatives. Then, the obtained product is halogenated to introduce chlorine atoms. Chlorine gas, sulfoxide chloride and other chlorinated reagents can often be used to achieve 6-position chlorination in the presence of a specific catalyst. Finally, the nitration reaction is carried out, and the mixed acid of concentrated nitric acid and concentrated sulfuric acid is used as the nitration reagent. At a suitable temperature range, the 3-position is introduced into the nitro group to obtain 6-chloro-3-nitropyridine-2-formonitrile.
Second, 2-cyanopyridine is used as the starting material. It is first nitrified to obtain 3-nitro-2-cyanopyridine. Then, chlorine atoms are introduced at the 6-position, and suitable chlorination reagents and reaction conditions can be selected. For example, under the action of light or a specific catalyst, the target product can also be obtained by reacting with a chlorine source.
Third, using other compounds containing pyridine rings as starting materials, cyano, chlorine atoms and nitro groups are gradually introduced through multi-step reactions. However, this path is often complicated, and the reaction steps and conditions need to be carefully designed to ensure the selectivity and yield of each step of the reaction.

When it comes to the melting point, 6-chloro-3-nitropyridine-2-formonitrile has a specific value. This melting point is the key basis for the identification and purification of this compound. However, many aromatic compounds containing similar nitrile groups and nitro groups have melting points between tens of degrees Celsius and more than 200 degrees Celsius, which can be used as a reference for speculation.
In terms of solubility, the solubility of 6-chloro-3-nitropyridine-2-formonitrile in organic solvents may be different. Generally speaking, it has good solubility in polar organic solvents such as dimethyl sulfoxide (DMSO) and N, N-dimethylformamide (DMF). Since the polarity of the two is strong, they can form intermolecular forces with the compound to promote dissolution. In non-polar organic solvents such as n-hexane and benzene, the solubility is poor, because its molecules are polar, and the interaction with non-polar solvents is weak. In water, although it contains polar groups, it can interact with water to a certain extent, but the overall molecular hydrophobicity is partially affected, and the solubility should be limited.
In addition, the density, boiling point and other physical properties of 6-chloro-3-nitropyridine-2-formonitrile are also affected by the chlorine atom, nitro group and nitrile group in the molecular structure. The relative mass of chlorine atoms is large, which will increase the molecular weight and improve the density. The presence of nitro and nitrile groups enhances the intermolecular force and affects the boiling point and other properties. However, the exact density and boiling point values also need to be accurately determined experimentally.
In summary, the physical properties of 6-chloro-3-nitropyridine-2-formonitrile are determined by its molecular structure. Although some accurate data need to be determined experimentally, they can be reasonably speculated and analyzed according to the properties and structural characteristics of similar compounds, which is of great significance for the study of its synthesis, separation and application.
