A highly efficient and eco-friendly protocol has been described for the synthesis of amidomethylarenes and -heteroarenes via one-pot three-component coupling reaction of amides, aldehydes and (hetero)arenes over a heterogeneous catalyst (Hβ zeolite) in solvent-free conditions. The scope and limitations of this catalytic process are demonstrated with various amides and arenes and the corresponding amidoalkylated
对于无溶剂条件下酰胺,醛和(杂)芳烃的一锅三组分偶联反应,已经描述了一种高效,环保的方案,用于酰胺基甲基芳烃和-杂芳烃的合成。 。用各种酰胺和芳烃证明了该催化方法的范围和局限性,并且以中等至优异的产率获得了相应的酰胺烷基化的芳烃产物。初步的力学见解(对照实验)表明,双酰胺和/或N-(羟甲基)苯甲酰胺可能是该反应的中间体。此外,该催化剂可以重复使用而不会显着降低催化活性,并且仅产生水作为副产物。
