Ligand-Free and Regioselectivity of the Heck Reaction Catalyzed by Pd(0) Nanoparticles at Ambient Conditions under Ultrasonic Irradiation

摘要：

The Heck reaction proceeded in isopropanol under ultrasonic irradiation at ambient temperature (30℃) has been reported in this report.The Heck reaction showed excellent regioselectivity,enhanced reaction rates,high yields,and the conditions were mild and environmentally friendly.It was found that as a heterogeneous catalyst for the reaction palladium forms nanoparticles in-situ,and can be recycled for many times.Transmission electron microscopy (TEM) and X-ray powder diffraction (XRD) analysis characteried the formation of stable,crystalline Pd(0) nanoparticles as catalyst for the reaction.
