γ-(β-氰乙硫基)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负载硫醚钯配合物. 该新型负载钯配合物是芳基卤化物的羰基化反应的有效催化剂, 为各种取代的N-苯基苯甲酰胺、苯甲酸丁酯的合成提供了方便实用的新途径.

MCM-41-supported thioether palladium complex has been prepared via immobilization of 3-(2-cyanoethylsulfanyl)propyltriethoxysilane on MCM-41, followed by reacting with palladium chloride. The complex is an efficient catalyst for Heck carbonylation of aryl halides with aniline or n-butyl alcohol under atmospheric pressure of carbon monoxide. A variety of substituted N-phenylbenzamides and n-butyl benzoates were prepared. Importantly, the complex can be recovered and reused without loss of activity.

Key words: MCM-41, supported palladium catalyst, thioether palladium complex, aryl halide, carbonylation
