摘要
γ氯丙基三乙氧基硅烷依次与气相法二氧化硅固载，二苯膦钾膦化，再与氯化钯反应，合成了聚γ（二苯膦基）丙基硅氧烷钯配合物。
A fume silica bound poly γ (diphenylphosphino)propylsiloxane palladium complex was synthesized from γ chloropropyltriethoxysilane and fume silica via hydrolysis,followed by phosphatization with potassium diphenylphosphide and then the reaction with palladium chloride.The title complex exhibited good catalytic activity for Heck carbonylation of aryl halides with aniline or butyl alcohol and can be reused without serious loss of activity.A possible structure pattern of this polymeric phosphine palladium complex has been suggested.
