| 摘 要： | 合成了纤维素乙二胺负载钯（CE—Pd）配合物，用IR、XPS、TG／DTA等手段对其进行了表征．该配合物在室温至280oC范围内有很好的稳定性，在空气氛围水相中能有效地催化丙烯酸与芳基碘、苯乙烯与芳基碘的Heck芳基化反应，立体选择性地生成取代的反式肉桂酸、1，2-二苯乙烯．在80℃时反应6h，反式肉桂酸的产率达89．7％．纤维素乙二胺负载钯（CE—Pd）配合物还具有较好的重复使用性能，连续使用4次，反式肉桂酸的产率仍可达到63．5％．

| Abstract: | The ethylenediamine cellulose supported palladium(0)complex was synthesized and characterized by IR,XPS,TG/DTA etc.The complex has good thermal stability from room temperature to 280 ℃ and found to be an efficient catalyst for Heck reaction of acrylic acid or styrene with aryl iodide at low temperature in water under atmospheric condition.The substituted trans-cinnamic acid or 1,2-stilbene was obtained with high yield at 80 ℃ and reaction time of 6 h.The ethylenediamine cellulose supported palladium(0)complex could be separated from the reaction mixture easily and reused for several cycles.The conversion could still go up to 63.5 % when the catalyst was run for 4 times. |
