In this five-membered ring, the nitrogen atom is attached to the ring by a single bond and conjugated with the double bond in the ring to increase its stability. The presence of dicarbonyl groups makes the molecule have a certain polarity and reactivity.
1,3-Phenediyl connects two 1H-pyrrole-2,5-dione groups to form a specific spatial configuration. The uniqueness of this structure makes this compound have special properties and uses in the fields of chemistry and materials.

1%2C1%27-%28benzene-1%2C3-diyl%29bis%281H-pyrrole-2%2C5-dione%29, this is the name of an organic compound, which has several important physical properties.
Looking at its morphology, under room temperature and pressure, it is mostly solid, because of its strong intermolecular forces, resulting in a tight and orderly arrangement of molecules. In addition, the melting point of this substance is quite high, and a higher temperature is required to convert it from solid to liquid. This is because there are forces such as conjugated systems and hydrogen bonds in the molecular structure, and more energy is required to break these effects.
In terms of solubility, it has a certain solubility in common organic solvents such as dichloromethane and chloroform. This is because the molecular structure of this compound has a similar polarity to these organic solvents, and it can be dissolved according to the principle of "similar miscibility". However, the solubility in water is extremely low, because water is a strong polar solvent, and the polarity of this compound is relatively weak, it is difficult to form an effective force between the two molecules.
Its density is slightly higher than that of common organic solvents, and it may sink to the bottom when placed in organic solvents. And this substance has good stability. Under normal conditions, the molecular structure is not easy to change. When encountering extreme conditions such as strong oxidants and strong acids and bases, chemical reactions may occur, causing structural changes. Its vapor pressure is very low, and its volatilization rate is slow at room temperature, which is also conducive to the safety of its storage and use.

1%2C1%27-%28benzene-1%2C3-diyl%29bis%281H-pyrrole-2%2C5-dione%29 in many fields such as materials, medicine, organic synthesis and dyes, all of which show important application value and potential development prospects.

1%2C1%27-%28benzene-1%2C3-diyl%29bis%281H-pyrrole-2%2C5-dione%29, that is, 1,1 '- (benzene-1,3-diyl) bis (1H-pyrrole-2,5-dione) also. The synthesis method covers many ways, and is described in detail as follows:
First, benzene-1,3-diamine and maleic anhydride are used as raw materials. First, place the two in a suitable reaction vessel in an appropriate ratio, and add an appropriate amount of organic solvent, such as N, N-dimethylformamide (DMF). This reaction needs to be carried out under mild heating conditions, such as between 60-80 ° C, when stirring for a number of times. During the reaction, the amino group of benzene-1,3-diamine and the carboxyl group of maleic anhydride undergo a condensation reaction, and gradually form the target product. After the reaction is completed, the product is separated in a suitable manner, such as reduced pressure distillation to remove the solvent, and then recrystallized to purify, to obtain a relatively pure 1,1 '- (benzene-1,3-diyl) bis (1H-pyrrole-2,5-dione).
Second, the benzene ring can be modified first. Using 1,3-dihalobenzene as the starting material, it reacts with the metal salt (such as sodium salt) of pyrrole-2,5-dione under basic conditions and in the presence of a phase transfer catalyst. When 1,3-dihalobenzene, pyrrole-2,5-dione sodium salt, basic substances (such as potassium carbonate) and phase transfer catalysts (such as tetrabutylammonium bromide) are placed in an organic solvent (such as toluene) and heated for reflux number. The nucleophilic substitution reaction occurs between the halogen atom of halobenzene and the activity check point of pyrrole-2,5-dione sodium salt to construct the target molecular structure. After the reaction, the product is purified by extraction, drying, column chromatography and other means.
Third, a coupling reaction strategy catalyzed by transition metals is adopted. Borate containing benzene-1,3-diyl and halopyrrole-2,5-dione are used as raw materials. In the reaction system, a transition metal catalyst (such as palladium catalyst), a ligand (such as tri-tert-butylphosphine) and a base (such as sodium carbonate) are added, and in an organic solvent (such as 1,4-dioxane), heated to an appropriate temperature (such as 80-100 ° C). This process realizes the connection of benzene-1,3-diyl and pyrrole-2,5-dione through the coupling mechanism of transition metal catalysis, and finally produces 1,1 '- (benzene-1,3-diyl) bis (1H-pyrrole-2,5-dione). Subsequent operations such as separation and purification are required to obtain purified products.
