摘　　要：4 氧杂 6 ,7 二氯庚基三甲氧基硅烷依次与气相法二氧化硅、甲硒基钠、氯化钯作用 ,合成了二氧化硅固载的聚 4 氧杂 6 ,7 二甲硒基庚基硅氧烷钯配合物 .它对芳基卤化物的Heck羰基化反应具有良好的催化活性 .A fume silica-supported poly-4-oxa-6, 7-dimethylselenoheptylsiloxane palladium complex has been prepared from 4-oxa-6,7-dichloroheptyltrimethoxysilane via immobilization on fume silica, followed by reacting with sodium methylselenolate and then the reaction with palladium chloride. The X-ray photoelectron spectroscopy ( XPS) has been used to characterize the palladium complex and a possible structure pattern of the polymeric palladium complex has been suggested. The title complex exhibits good catalytic activity in Heck carbonylation of aryl halides with aniline or butyl alcohol under atmospheric pressure of carbon monoxide. When aryl iodides are used as the substrates, the substituted N-phenylbenzamides or butyl benzoates are obtained in good to high yields. This polymeric bidentate selenide palladium catalyst can be recovered and reused without serious loss of activity. Hence this paper presents a simple and practical synthetic method for the substituted N-phenylbenzamides and butyl benzoates.
