| Popis: | A ceria nano catalyst was used for the one-pot, multi-component condensation reaction of benzoylacetonitrile, aromatic aldehydes and 5-aminotriazole/5-aminotetrazole, and proceeds via C–C and C–N bond formation to deliver the desired triazolo/tetrazolo[1,5-a]pyrimidine derivatives. This protocol provides cleaner conversion with high selectivity and shorter reaction times. The CeO2 nanoparticles were prepared by a simple coprecipitation method and characterized using XRD, TEM, and XPS techniques. |
