The synthesis of (eta(3)-C3H5)Pd{Si[N(Bu-t)CH](2)}Cl and the catalytic property for Heck reaction

Treatment of N-heterocyclic silylene Si[N(Bu-t)CH](2) (1) and [(eta(3)-C3H5)PdCl](2) in toluene led to the formation of the mononuclear complex (eta(3)-C3H5)Pd{Si[N(Bu-t)CH](2)}Cl (3), the silicon analogue to N-heterocyclic carbene complex (eta(3)-C3H5)Pd{C[N(Bu-t)CH](2)}Cl (2). Complex 3 was characterized with H-1 NMR and C-13 NMR. Investigation shows that (eta(3)-C3H5)Pd{Si[N(Bu-t)CH](2)}Cl is an active catalyst for Heck coupling reaction of styrene with aryl bromides.
