A highly efficient and simple synthesis of 2,4,5-trisubstituted imidazoles has been developed using highly reusable support‐free Mn2+complex of [7-hydroxy-4-methyl-8-coumarinyl] glycine as a heterogeneous catalyst via a one-pot three-component reaction of benzil, aldehydes and ammonium acetate as a nitrogen source. Moreover, this catalyst was characterized by various techniques such as field emission
使用高度可重复使用的 [7-hydroxy-4-methyl-8-coumarinyl] 甘氨酸的 Mn 2+ 配合物作为非均相催化剂,开发了一种高效且简单的 2,4,5-三取代咪唑合成方法。- 苯偶酰、醛类和乙酸铵作为氮源的锅三组分反应。此外,该催化剂通过场发射扫描电子显微镜(FE-SEM)、能量色散X射线光谱(EDX)、FT-IR光谱、粉末X射线衍射(XRD)、电感耦合等离子体( ICP)和热重分析(TGA)。此外,该催化剂是稳定的,可以重复使用至少六次而不会显着丧失活性。 图形摘要
