To prepare 2,2-bis (2-cyanophenyl) -4,4,5,5-tetraphenyl-1,2-biimidazole, the following ancient method can be used.
First take an appropriate amount of 2-cyanobenzaldehyde and place it in a clean reactor, supplemented by a suitable organic solvent, such as anhydrous ethanol, to fully dissolve it. This organic solvent needs to be dried in advance to remove moisture and avoid side reactions.
Prepare an appropriate amount of o-phenylenediamine, also soluble in an organic solvent, and slowly pour it into the reactor containing 2-cyanobenzaldehyde. During the process, stir at a constant speed with a stirring instrument to make the two fully mixed. < Br >
Then, the temperature of the reaction system is slowly raised to a specific value, between about 120 and 150 degrees Celsius, and this temperature is maintained for several hours. During the reaction, close attention should be paid to changes in the reaction system, such as color changes, precipitation formation, etc.
After the reaction is completed, the reaction mixture is naturally cooled to room temperature. Then, the organic solvent is removed by vacuum distillation. The residue is recrystallized with a suitable recrystallization solvent, such as ethanol-water mixed solvent. After multiple recrystallization, pure 2,2-bis (2-cyanophenyl) -4,4,5,5-tetraphenyl-1,2-imidazole crystals can be obtained.
When operating, be sure to strictly follow the procedures and pay attention to safety. Organic solvents are flammable and volatile, so open flames must be avoided around. And the control of reaction temperature and the dosage of each material must be accurate to obtain the ideal product.
