Abstract: Asilica-supported poly γ-mercaptopropylsiloxane palladium(0) complex was prepared from γ-mercaptopropyltriethoxysilane and fume silica via hydrolysis, followed by treatment with palladium chloride in acetone and then the reduction with hydrazine hydrate in ethanol. It was found that the title complex is an efficient catalyst for Heck arylation of acrylamide and butyl acrylate. This polymeric palladium(0) catalyst is stable and can be reused without noticeable loss of activity.
Key words: Polymeric palladium catalyst, Sulfur palladium complex, Heck arylation, Stereo-selective synthesis
