graphene oxide supported copper oxide (CuO–GO) has been investigated in Click synthesis of 1,2,3‐triazole derivatives under green reaction conditions. In the context of green approach, water is used as solvent under ligand free and aerobic conditions at room temperature, with low catalyst loading (0.2 mol %) while ensuring the recovery and reusability of the catalyst. The catalyst affords excellent selectivity
在绿色反应条件下,点击合成1,2,3-三唑衍生物时,已经研究了氧化石墨烯负载的氧化铜(CuO-GO)的催化活性。在绿色方法的背景下,在无配体和需氧条件下,室温下将水用作溶剂,催化剂负载量低(0.2 mol%),同时确保催化剂的回收和可重复使用性。该催化剂在形成所需产物方面具有优异的选择性,产率高至优异。此外,这里采用的后处理程序既干净又简单,同时可以回收用于后处理程序的有机溶剂。提出存在于GO表面上的官能团对于防止反应期间催化活性氧化铜物质的聚集是有效的。而且,
