Related Products of 611-09-6, These common heterocyclic compound, 611-09-6, name is 5-Nitroindoline-2,3-dione, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: 30 mg of SiO2_g-C3N4 nanocomposite was dispersed in aqueous media (3 ml) for 30 min and dimedone or 4-hydroxycoumarin (1 mmol), malononitrile (1 mmol) and isatin (1.0 mmol) were added to the mixture. Then, the mixture was stirred at reflux conditions for an appropriate time, while the reaction progress was monitored by thin layer chromatography (TLC). After the reaction was completed, ethyl acetate was employed for the extraction of crude product and the products were dried over anhydrous Na2SO4. The solvent was evaporated followed by recrystallizing of the crude product in hot ethanol, and pure products were identified by IR, 1H and 13C NMR spectral data. The SiO2_g-C3N4 nanocatalyst was washed with EtOH, dried and reused for the next run.
Statistics shows that 5-Nitroindoline-2,3-dione is playing an increasingly important role. we look forward to future research findings about 611-09-6.
