Synthesis of PEG Supported Palladium Nanoparticles: Simple and recyclable palladium catalytic system for Heck reaction

Palladium nanoparticles with narrow size distribution as a catalytic system for Heck reaction were synthesized by applying poly(ethyleneglycol) (PEG) and Pd(OAc)2. PEG acts as a reducing agent for reduction of Pd2+ to Pd and also as a stabilizer for synthesized palladium anoparticles. Both XRD and TEM results exhibit production of nanoparticles with about 7nm in diameter. This polymeric palladium catalyst is relatively inexpensive, environmentally benign, and simply functionalizable and can be easily recovered from the products.
