Abstract

This research developed a new nanocatalyst by incorporating nanocopper iodide onto the surface of a layered double hydroxides modified. This new nanocatalyst enables the green synthesis of tetrahydrobenzo[]pyrans and 2-amino-4-chromene derivatives through a one-pot, three-component reaction, demonstrating remarkable activity and selectivity. Key advantages of this method include increased products yield (86-96%), rapid reaction kinetics (5-23 minutes), low reaction temperature (40 °C), synthesis of new products, straightforward purification methods, catalyst recyclability (up to 4 cycles), and solvent-free conditions.

摘要

本研究通过将纳米碘化铜负载到改性层状双氢氧化物表面，制备了一种新型纳米催化剂。这种新型纳米催化剂能够通过一锅三组分反应实现四氢苯并[]吡喃和2-氨基-4-色烯衍生物的绿色合成，展现出显著的活性和选择性。该方法的主要优点包括提高产物收率（86-96%）、快速的反应动力学（5-23分钟）、较低的反应温度（40℃）、合成新产物、纯化方法简便、催化剂可循环使用（高达4次循环）以及无溶剂条件。
