Abstract :

Xanthenes and benzos Xanthenes are important heterocyclic systems and also have biological and pharmacological properties, such as antibacterial properties against the virus. In this study, FeNi3 / SiO2 / PPA nanoparticles were synthesized as solid acid support for the synthesis of multicomponent reaction of tetrahydrobenzo[a]xanthene-11-ones in solvent-free conditions. The reaction of tetrahydrobenzo[a]xanthene-11-ones with 1gr of the catalyst was achieved in high yield products at 120 ° C without solvent and temperature. FeNi3 / SiO2 / PPA nanoparticles were confirmed by IR, TEM, SEM and EDX spectroscopy. The results showed that the catalyst has high activity, environmentally friendly, heterogeneous and can be easily recovered from the reaction mixture without losing its catalytic activity.
