Abstract A silica‐supported arsine palladium(0) complex has been prepared from γ‐chloropropyltriethoxysilane via im‐mobilization on fumed silica, followed by reaction with potassium diphenylarsenide and palladium chloride, and then reduction with hydrazine hydrate. The complex has been characterized by X‐ray photoelectron spectroscopy (XPS) and it is a highly active and stereoselective catalyst for arylation of butyl acrylate and acrylamide with aryl halides, affording a variety of trans ‐butyl cinnamates and trans ‐cinnamamides in high yields.
