Abstract
A new catalytic system based on Pd-NHC complex utilizing (4-pyridyl)bis(imidazolyl)methane as a bidentate NHC ligand supported on nano. silica is introduced. The catalyst was characterized by FT-IR spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy, energy dispersive X-ray analysis, transmission electron microscopy and elemental analysis. This heterogeneous catalytic system exhibited excellent activity in the Suzuki-Miyaura coupling reaction of various aryl halides with phenylboronic acid, and was reusable several times without significant loss of its catalytic activity.
