A new magnetic nano-catalyst system based on graphene oxide was designed and manufactured (GO@FeO@3-chloropropyltrimethoxysilane@(Z)-N'-(2-hydroxybenzylidene)-4-(pyridin-4-yl)benzohydrazide@Cu(II)), and it was checked and confirmed by various analyzes such as FTIR, XRD, EDX, MAPPING, TGA/DSC, VSM and FESEM. This nano-catalyst was used in the three-component one-pot synthesis of quinazoline derivatives. The products were obtained using this efficient catalyst with high efficiency in short time and solvent-free conditions. Easy separation and acceptable recyclability are other advantages of this new nano-catalyst. Also, the catalyst can be recycled 4 times without a significant change in its efficiency.
设计并制造了一种基于氧化石墨烯的新型磁性纳米催化剂体系（GO@FeO@3-氯丙基三甲氧基硅烷@(Z)-N'-(2-羟基亚苄基)-4-(吡啶-4-基)苯甲酰肼@Cu(II)），并通过FTIR、XRD、EDX、MAPPING、TGA/DSC、VSM和FESEM等各种分析对其进行了检测和确认。该纳米催化剂用于喹唑啉衍生物的三组分一锅法合成。使用这种高效催化剂可在短时间内无溶剂条件下高效获得产物。易于分离和可接受的可回收性是这种新型纳米催化剂的其他优点。此外，该催化剂可循环使用4次，其效率无显著变化。
