Synthesis catalytic activity and leaching studies of a heterogeneous Pd-catalyst including an immobilized bis(oxazoline) ligand

摘要

Graphical abstractA catalytic system including a Pd(OAc)2-bis(oxazoline) complex bonded to 3-mercaptopropyl-functionalized silica gel is presented. The catalyst was tested for Suzuki–Miyaura reactions. The heterogeneity of the catalytic system was studied indicating that there is virtually no Pd-leaching. Furthermore, the catalyst can be reused multiple times without significant loss of stability or structure.
