We report the synthesis of a superparamagnetic nanoparticle MNP (γ-Fe(2)O(3)/polymer) supported dendritic catalyst based on a bulky electron-rich phosphine Pd(II) complex. The high reactivity of this catalyst is described in a copper-free Sonogashira C-C cross-coupling reaction in water, and the significant role of surfactant additives is highlighted in the recovery study.
我们报告了一种超顺磁纳米粒子 MNP(γ-Fe2O3/聚合物)负载树枝状催化剂的合成,该催化剂基于一个庞大的富电子膦 Pd(II) 配合物。该催化剂在无铜 Sonogashira C-C 交叉偶联反应中的高反应活性得到了描述,并强调了表面活性剂添加剂在回收研究中的重要作用。
