Abstract

A general procedure has been developed for the rapid synthesis of 8-aryl-7H-acenaphtho[1,2-d]imidazoles in high yields using Fe₃O₄ NPs@GO@C₄H₈SO₃H as a green and recyclable magnetic nanocatalyst under reflux conditions. The nanocatalyst was prepared and characterized by FT-IR, XRD, and EDX data. A variety of aromatic aldehydes underwent condensation with NH₄OAc and acenaphthenequinone to give 8-aryl-7H-acenaphtho[1,2-d]imidazole derivatives. The use of magnetic nanoparticles, easy separation of the catalyst with an external magnet, high yields, and short reaction times are the main advantages of this catalytic method.

摘要

已经开发了一种通用方法，可以使用Fe ₃ O ₄ NPs @ GO @ C ₄ H ₈ SO ₃ H作为绿色有机化合物快速合成高产率的8-芳基-7 H -ac [1,2- d ]咪唑。回流条件下可回收的磁性纳米催化剂。制备了纳米催化剂，并通过FT-IR，XRD和EDX数据对其进行了表征。各种芳香醛与NH ₄ OAc和啶醌缩合，生成8-芳基-7 H -ac [1,2- d]咪唑衍生物。磁性纳米粒子的使用，催化剂与外部磁体的容易分离，高收率和较短的反应时间是该催化方法的主要优点。
