| Popis: |
A metal-free, efficient, and eco-friendly on-water protocol for the synthesis of quinazolinone derivatives via a tandem one-pot three-component reaction using a novel, efficient, and recyclable heterogeneous catalyst, [CA@MIP] – melamine-based covalent organic polymer supported citric acid, has been described. The catalyst has been synthesized by a simple procedure and is well characterized by numerous spectroscopic techniques such as Fourier Transform Infrared (FTIR), Scanning Electron Microscope (SEM), Powder X-ray diffraction (PXRD), Brunauer-Emmett-Teller (BET), Energy Dispersive X-ray (EDX), and Thermal Gravimetric (TG) analyses. [CA@MIP] showed excellent catalytic potential offering quinazolinones in excellent yields (>85%) in a short reaction time period and was reusable for up to five successive runs. |
