摘　　要：γ-巯丙基三乙氧基硅烷依次用纳米介孔分子筛(MCM-41)固载,与氯化钯反应,合成了MCM-41负载巯基钯配合物.该新型负载钯配合物是芳基卤化物羰基化反应的有效催化剂,能重复使用多次活性基本不变,为各种取代的N-苯基苯甲酰胺、取代的苯甲酸丁酯的合成提供了新途径.A simple and practical synthetic method for a variety of substituted N- phenylbenzamides and nbutyl benzoates was presented. MCM-41-supported mercapto palladium complex has been prepared from γ- mercaptopropyhriethoxysilane via immobilization on MCM-41, followed by reacting with palladium chloride. The title complex is an efficient catalyst for Heck carbonylation of aryl halides with aniline or nbutyl alcohol under atmospheric pressure of carbon monoxide and can be recovered and reused without loss of activity.
