Abstract :
In recent years, significant progress has been made in the use of non-toxic, recyclable, available and affordable CO2 for the production of organic composites. The goal of this research is to synthesize NiCo2O4 nanoparticles and investigate their performance on the three-component and efficient reaction of 3a, 4-dihydronaphtho [2, 3-c] furan-1(3H)-one. The structure and morphology of nanoparticles were analyzed by EDX, TEM, SEM, FT-IR and XRD analysis and the effect of various parameters such as solvent, temperature, time, amount of catalyst and substrate on the process of reactions was investigated. The results showed that the reaction of 3a,4-dihydronaphtho[2,3-c]furan-1(3H)-one, at a temperature of 60℃, with 8 mg of NiCo2O4 NPs catalyst and without solvent in the presence of electron-donating alkynes, had 94% efficiency. Catalysts can be recycled; NiCo2O4 Nano catalysts are separated from the solvent by a magnet. After 10 uses, their performance decreased slightly. The nanoparticles used have outstanding properties such as thermal stability, high mechanical properties, good active sites, and a very large contact surface, allowing them to be used in several reactions.
