Afume silica supported poly γ ( β cyanoethylsulfenyl) propylsiloxane palladium(0) complex was synthesized from poly γ ( β cyanoethylsulfenyl) propylsiloxane andpalladium chloridein acetone,followed by reduction with hydrazine hydrate in ethanol. Thestructure ofthis complex wascharacterized by elementalanalysis and X P S. It wasfound thatthe title complex is an efficient catalyst for Heck arylation of acrylamide and butylacrylate . This polymeric palladium(0) catalystis stableto air and can be reused without noticeablelossof activity . Hence this paper presents a simple and practicalstereo selective synthetic methodfor substituted trans cinnamamides and trans butyl cinnamates.
