摘 要:研究了有机/SiO2杂化材料负载的钯配合物催化剂和对碘代苯与丙烯酸Heck交叉偶联反应的催化性能,考察了不同条件对该反应的影响.结果表明:催化剂具有较高的催化活性和立体选择性,可以高转化率、高产率地合成反式肉桂酸,且催化剂经过滤洗涤可回收再利用.同时探讨了催化剂对其他反应底物的催化性能.A organic/silica hybrid material surpported palladium catalyst is studied. Using the reaction between iodobenzene and acrylic acid as a model,the activity of this catalyst is studied. The effect of different reaction conditions on the yield are investigated. The result shows that the catalyst has high catalytic activity and regionselectivity for the synthesis of trans-phenylacrylic acid. The catalyst earl be recovered by filtration and washing with solvent, and reused for many times. The Heek arylation reactions of other suhstrates catalyzed by the catalyst also investigated.
