Abstract

A silver nanocatalyst has been used as an effective catalyst for the preparation of quinazolinones under reflux conditions in ethanol. The catalyst was characterized by UV-VIS, FT-IR, XRD, SEM and EDS. Amongst the many benefits of this method are atom economy, reusability of the catalyst, low catalyst loading, applicability to a wide range of substrates, high yields of products, environmental friendliness and easy separation of products. Silver nanoparticles (Ag NPs) were prepared using extract. The structures of the prepared quinazolinones were fully characterized by H and C NMR, FT-IR spectra and elemental analysis.

摘要

一种银纳米催化剂已被用作在乙醇回流条件下制备喹唑啉酮的有效催化剂。该催化剂通过紫外可见光谱（UV-VIS）、傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、扫描电子显微镜（SEM）和能谱分析（EDS）进行了表征。该方法的诸多优点包括原子经济性、催化剂的可重复使用性、低催化剂负载量、对多种底物的适用性、高产物收率、环境友好性以及产物易于分离。使用提取物制备了银纳米颗粒（Ag NPs）。通过氢核磁共振（H NMR）、碳核磁共振（C NMR）、傅里叶变换红外光谱（FT-IR）和元素分析对所制备的喹唑啉酮的结构进行了全面表征。
