In this paper, we report a simple, facile and efficient method for the synthesis of Fe3O4/SiO2‐DTZ‐Pd. The immobilized palladium was an efficient catalyst without addition of phosphine ligands for Stille, Heck and N‐arylation reactions. This method has some advantages such as high yields and easy work up of products. In addition, the catalyst can be recovered using a magnet and reused several times

钯是一种有效的催化剂,无需添加用于Stille,Heck和N-芳基化反应的
膦配体。该方法具有诸如高收率和易于产品加工的优点。另外,可以使用磁体回收催化剂并重复使用几次,而不会显着降低其催化活性。该催化剂具有多种物理
化学技术的特征,例如扫描电子显微镜(
SEM),透射电子显微镜(
TEM),X射线衍射(XRD)和电感耦合等离子体(ICP)。
