5(6)-Nitrobenzimidazole

5- (2-nitrophenyl) -286-nitrobenzimidazole, this is an organic compound. Its chemical structure is quite complex and interesting.
Benzimidazoles are based on benzimidazole. Benzimidazole is formed by fusing a benzene ring with an imidazole ring. The imidazole ring is a five-membered heterocycle containing two nitrogen atoms and is aromatic. The benzene ring is a six-membered carbon ring and also has aromatic properties. When the two fuse, benzimidazole is given unique chemical properties.
In this compound, the 5-position and the 286-position are connected to the nitrophenyl group and the nitro group, respectively. Nitro group (-NO ²) is a strong electron-absorbing group, which has a great influence on the electron cloud distribution of the benzimidazole ring. It will reduce the electron cloud density of the benzimidazole ring, which in turn affects the chemical activity and stability of the compound.
(2-nitrophenyl) connected at the 5-position is connected to the benzimidazole ring through chemical bonds. The nitro group in the 2-nitrophenyl group is in the phenyl ring ortho-position, and the spatial structure and electronic effects of the compounds following pair at this position also affect. The ortho-nitro group will significantly reduce the electron cloud density of the benzimidazole ring ortho-position, and may also trigger a steric hindrance effect and affect the interaction between molecules.
The nitro group attached to the 286-position also has an effect on the overall structure. The presence of two nitro groups greatly changes the electron cloud distribution of the benzimidazole ring, resulting in the compound exhibiting unique properties in chemical reactions, such as nucleophilic substitution and electrophilic substitution reactivity, etc., which are very different from unsubstituted benzimidazole due to the presence of nitro groups.
In short, the chemical structure of 5- (2-nitrophenyl) -286-nitrobenzimidazole is composed of benzimidazole ring and nitrophenyl group connected at specific positions. Each part affects each other, giving it unique chemical properties and reactivity.

5% 286% 29 - Nitrobenzimidazole, that is, 6 - nitrobenzimidazole, this is an organic compound. Its main physical properties are as follows:
1. ** Appearance properties **: Usually light yellow crystalline powder. This morphology is easy to observe and operate, and the light yellow color may suggest the electronic transition characteristics of its molecular structure.
2. ** Melting point **: about 273 - 276 ° C. The higher melting point indicates that the intermolecular force is strong, which may be attributed to the conjugated structure of the benzimidazole ring and the electronic effect of the nitro group, which enhances the intermolecular interaction and requires higher energy for melting.
3. ** Solubility **: Slightly soluble in water, soluble in common organic solvents such as dimethylformamide (DMF), dimethyl sulfoxide (DMSO), etc. Slightly soluble in water, because its molecular polarity is relatively small, and the force between water molecules is weak; while soluble in polar organic solvents, because these solvents can form interactions with 6-nitrobenzimidazole molecules, such as hydrogen bonds or van der Waals forces.
4. ** Stability **: relatively stable under conventional conditions, but in case of strong oxidants, strong acids, strong bases, or reactions. The stability of the benzimidazole ring is affected by the nitro group, which has electron-absorbing properties, which decreases the electron cloud density of the benzene ring and affects the reactivity to a certain extent. Therefore, the stability changes when encountering specific chemical substances.

5% 286% 29 - Nitrobenzimidazole is 5 (6) -nitrobenzimidazole. The common synthesis methods are as follows:
The starting materials are mostly o-phenylenediamine and oxalic acid or their derivatives.
First, use o-phenylenediamine and oxalic acid as raw materials, in a suitable solvent, such as ethanol or a water-ethanol mixed system, heat and stir. This is a classic condensation reaction. The two amino groups in o-phenylenediamine are condensed and dehydrated with the two carboxyl groups of oxalic acid to form a benzimidazole ring. The reaction requires precise temperature control, generally controlled at 100-150 ° C. If the temperature is too low, the reaction will be slow, and if it is too high, it will easily cause side reactions. After this step of the reaction is completed, the benzimidazole intermediate is
Then the intermediate is introduced into the nitro group by nitration reaction. Concentrated nitric acid and concentrated sulfuric acid are often mixed as nitrifying reagents. The intermediate is slowly added to the cooled mixed acid, and the temperature is strictly controlled at 0-5 ° C to prevent the nitro substitution position from getting out of control and excessive nitrification. At the end of the reaction, 5 (6) -nitrobenzimidazole can be obtained through purification steps such as neutralization, extraction, and recrystallization.
Second, phthaleamine is first reacted with oxalyl chloride. The activity of oxalyl chloride is higher than that of oxalic acid. The reaction is easier to proceed and the conditions are mild. Similarly, in a suitable organic solvent, such as dichloromethane, it can be stirred at room temperature. After forming the intermediate, the subsequent nitrification steps are consistent with the above, and In the
synthesis process, the control of reaction conditions, raw material ratio and purification methods are all crucial, which affect the purity and yield of the product.
