Nanopalladium immobilized on aminoethanol-functionalized poly(vinyl chloride): an easily prepared, air and moisture stable catalyst for Heck reactions

The Pd nanoparticles with narrow size distribution immobilized on the polymer surface of poly(vinyl chloride) supported 2-aminoethanol (PVC-AE) were achieved by a simple procedure applying the corresponding functionalized polymer and PdCl₂ in ethanol. The as-prepared catalyst (PVC-AE-Pd⁰) was found to be air and moisture stable and exhibits significant catalytic activity for Heck reactions under mild operating conditions. Furthermore, the catalyst can be easily recovered by simple filtration and reused for at least 6 cycles without losing its activity.
