CATALYTIC ACTIVITY OF TIO2 NANOPARTICLES IN THE SYNTHESIS OF SOME 2,3-DISUBSTITUTED DIHYDROQUINAZOLIN-4(1H)-ONES

Abstract

Green chemistry is playing an important role for synthesizing organic compounds, due to its eco-friendly nature and low cost. In green chemistry, metal nanoparticles exhibited some useful physical and chemical properties (catalytic activity). Due to its diverse properties, nanoparticles can be utilized as a catalyst in various organic reactions. Recent research has been directed towards the utilization of eco-friendly and bio-friendly plant materials in nanoparticles synthesis. In our present work, TiO2 nanoparticles (TiO2 NPs) were synthesized using Annona squamosa peel extract and their catalytic applications were studied on the 2,3-disubstituted dihydroquinazolin-4(1H)-one synthesis. Synthesized compounds were confirmed using FT-IR, 1H NMR, 13C NMR and GC–MS analyses.
