摘要：
Polystyrylphosphine-Pd(0) and silica supported polysiloxane-phosphine-Pd(0) complexeswere synthesized and characterized. Their catalytic properties for the decarboxylation of allyl β-keto esters were investigated. It was found that these complexes have good catalytic activities undermild condition for this decarboxylation in which many novel unsaturated ketones were obtained.The selectivity of this catalytic decarboxylation depends on the polymer ligand and the P/Pd ratioof catalyst. The stabilities of polymer phosphine-Pd(O) complexes catalysts are better than theirhomogeneous analogue.
