The Pd nanoparticles with narrow size distribution embedded on the polymer surface of poly(vinyl chloride)-supported an inexpensive and simple bidentate ligand 2-mercaptobenzothiazole (PVC-MBT) were achieved by a simple procedure applying the corresponding functionalized polymer and PdCl2 in the ethanol solution. The as-prepared catalyst (PVC-MBT-Pd(0)) was found to be air and moisture stable and exhibits significant catalytic activity for Suzuki-Miyaura reactions under milder operating conditions. The catalysts showed excellent activity towards Suzuki-Miyaura coupling reaction of different aryl iodides and bromides with phenyl boronic acid using ethanol as solvent in short reaction times. Furthermore, the catalyst can be easily recovered by simple filtration and reused for at least 5 cycles with comparable yields.

Keywords: nanopalladium; poly(vinyl chloride); 2-mercaptobenzothiazole; bidentate ligand; Suzuki-Miyaura reaction
