Application of 1080-74-6, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1080-74-6, name is 2-(3-Oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile, This compound has unique chemical properties. The synthetic route is as follows.
Add 4,4-((([2,1,3] -benzoseladiazole-4,7-substituent bis (4-dodecylthiophene-5,2-substituent)) di (4, 1-phenylene)) bis (aniline) dibenzaldehyde (737mg, 0.599mmol) and 3- (dicyanomethylene) indone (348.7mg, 1.797mol) were added to a 100ml round bottom flask,Add 80 ml of trichloromethane and 10 ml of pyridine. After reacting at room temperature for 6 hours, pour the reaction solution into ethanol to precipitate a large amount of blue-black solids at this time, filter, dissolve the solid with dichloromethane, and purify by column chromatography. Methane: petroleum ether = 3: 1 was used as an eluent to separate the crude product, and then recrystallized from dichloromethane and ethanol to obtain a blue-black powdery solid (345 mg, 36.5%). The blue-black powdery solid is IND-TPA-Th-BSe, and its NMR experimental data is as follows:
The chemical industry reduces the impact on the environment during synthesis 2-(3-Oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile. I believe this compound will play a more active role in future production and life.
