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 XPS. It wasfound thatthe title complex is an efficient catalyst for Heck arylation of acrylamide and butylacrylate . This polymeric palladium(0) catalystis stable to air and can be reused without noticeable loss of activity.Hence this paper presents a simple and practical stereo-selective synthetic method for substituted trans-cinnamamides and trans-butyl cinnamates.
