Green Synthesis of Dy2Sn2O7 Nanostructures Employing Gum of Ferula Assa Feotida for Formation of N3-substituted Quinazoline-2,4(1H,3H)- diones

Introduction: Dy2Sn2O7 nanoparticles (Dy2Sn2O7 NPs) were generated in the attendance of rheum gum, papaver somniferum gum, ferula assa feotida gum, barberry juice from Dy(NO3)3·5H2O and SnCl4·5H2O. Methods: The study of the structure of the specimens verified the generation of nanocatalysts in the scope of 20±5 nm. Synthesized catalysts with a variety of natural compounds were investigated by employing various methods. The characteristics of Dy2Sn2O7 were determined by SEM, TEM, EDX, and XRD. Due to the persistent colloidal stability, high mechanical, thermal sustainability, and high ionic internal character, the system can be deemed as an efficient catalyst by deploying the guest-host approaches. Results: Using industrial waste as raw materials and turning it into valuable products is an important phenomenon in green chemistry. Carbon dioxide is among these substances. This substance is less reactive and it is difficult to use them in a reaction. Conclusion: We announce the employment of CO2, isocyanides, and o-halo anilines in a multicomponent reaction for the production of quinazolines in the participation of Dy2Sn2O7 as a nanocatalyst.
