presented as an efficient, and reusable magnetically heterogeneous catalyst for the C‐O coupling reaction, namely Ullmann condensation reactions in an aqueous medium. This heterogeneous catalyst shows superior reactivity for the C‐O arylation of different aryl halide (chloride, bromide, and iodide) with phenol derivatives to afford the desired products in good to excellent yields within short reaction
固定在磁性纳米颗粒钯纳米@ 2-氨基- ñ - (2-氨基乙基)苯甲酰胺(的MNP @ A- Ñ -AEB.Pd 0)已经被提出作为用于C-O耦合一个高效,和可重复使用磁力的非均相催化剂反应,即在水性介质中的乌尔曼缩合反应。这种非均相催化剂对不同的芳基卤化物(氯化物,溴化物和碘化物)与酚衍生物的C-O芳基化反应显示出优异的反应活性,从而在较短的反应时间内以良好的产率提供所需的产物。而且,该催化剂可以容易地回收并重复使用七次而不会损失催化活性。通过多种技术对催化剂进行了表征,例如FT-IR,SEM,TEM,EDS,XRD,TGA和ICP-OES。
