[聚(苯乙烯)联吡啶]钯(o)是一种高分子负载的加氢催化剂,本文用紫外—可见漫反射光谱、光电子能谱和电子显微镜对其进行了表征,探索了它在芳基碘化物的乙烯基化反应中的应用,发现它的催化活性可与均相催化剂相比,并在三次使用中无明显降低。用这种催化剂合成了一系列取代二苯乙烯、取代肉桂酸和肉桂酸甲酯。 [Poly (styrene) dipyridyl] palladium (o) is a polymer supported hydrogenation catalyst, which is characterized by UV-Vis diffuse reflectance spectroscopy, photoelectron spectroscopy and electron microscopy. It is found that its catalytic activity can be compared with the homogeneous catalyst and has not been significantly reduced in three uses. A series of substituted stilbenes were synthesized using this catalyst, replacing cinnamic acid and methyl cinnamate.
