A highly stable and very active heterogeneous Pd nanocatalyst in the O-arylation of phenol or C-O cross couplings.

An efficacious and reusable heterogeneous Pd Porphyrin nanocatalyst with high potentials in catalysis was prepared and characterized. The Pd Porphyrin nanocatalyst exposed excellent exertions and reusabilities in aqueous phase processes including the O-arylation of phenol or C-O cross coupling. The superior utility of Pd Porphyrin nanocatalyst in catalysis was elucidated by the broad scope of the reactants, mild reaction condition and the excellent yields (95-98%) of the reaction products. This Pd Porphyrin nanocatalyst was characterized by energy dispersive X-ray spectroscopy (EDX), X-ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), and ICP analysis. All of these manners confirm the nanocatalyst was built.[1]
