Zeolites, which are nontoxic, abundant, and cheap, are very promising supports for the design and preparation of new and environmentally benign catalysts. In this study, Cu nanoparticles (NPs) were immobilized on the surface of natural Natrolite zeolite by Anthemis xylopoda flowers aqueous extract as a reducing and stabilizing agent. Afterward, the catalytic performance of the prepared catalyst was investigated for N-formylation of amines at room temperature under environmentally benign reaction conditions. The catalyst could be reused at least 5 times without any decrease in activity. The advantages of the present protocol include the use of green catalyst, easy isolation of the products, reusability of catalyst, absence of nontoxic reagents, and excellent yield of the products.
沸石无毒、储量丰富且价格低廉，是设计和制备新型环境友好型催化剂非常有前景的载体。在本研究中，通过西洋甘菊花水提取物作为还原剂和稳定剂，将铜纳米颗粒（NPs）固定在天然钠沸石的表面。之后，在环境友好的反应条件下，研究了所制备催化剂在室温下用于胺的N-甲酰化反应的催化性能。该催化剂可重复使用至少5次，活性无任何下降。本方法的优点包括使用绿色催化剂、产物易于分离、催化剂可重复使用、不存在无毒试剂以及产物收率优异。
