中文摘要：
含溴原子的环钯化合物[PdCl{[（η5-C5H5）]Fe[（η5-C5H3）-NC5H3-Bd}（C3N2H2）（C6H]-2C3H7）2]}（化合物1）与聚乙二醇（PEG）-10000反应，合成出聚乙二醇负载氮杂环卡宾环钯化合物1-PEG（10000）．用红外光谱和核磁共振对其结构进行表征．以水为溶剂，K3PO。为碱，1-PEG（10000）能高效催化各种氯代芳烃的Suzuki偶联反应，该催化体系循环使用3次，还能保持较高的催化活性．
英文摘要：
Polyethylene glycol-supported N-heterocyclic carbene palladium complex [ 1 -PEG（10000） ] have been prepared from [PdCl{[（η5-C5H5）]Fe[（η5-C5H3）-NC5H3-Bd}（C3N2H2）（C6H]-2C3H7）2]}1 and PEG- 10000. The compound has been characterized by infrared spectroscopy and 1H NMR. Using 1 -PEG（10000） as catalyst in the presence of K3PO4 as base in water at 100℃ provided coupling products in excellent yields. Moreo- ver, the above system could be recycled and reused three times.
