摘要/Abstract
聚乙二醇（PEG）可以溶解多种有机物和金属配合物，具有良好的热稳定性、难挥发、无毒、能生物降解、廉价易得，易于回收和循环使用.PEG作为绿色介质已经成功地应用到许多有机反应中，如碳-碳偶联反应、碳-杂偶联反应、多组分反应、缩合反应、加成反应、取代反应、氧化反应、还原反应等.总结了近年来PEG作为反应介质在不同有机反应中的应用情况.

Polyethylene glycols (PEG) can dissolve a lot of organic compounds and metallic complexes. Moreover, they are thermally stable, nonvolatile, non-toxic, biodegradable, inexpensive and recyclable. Thus, PEG as green medium has been successfully employed in many organic reactions, such as carbon-carbon coupling reaction, carbon-hetero coupling reaction, multicomponent reaction, condensation reaction, addition reaction, substitution reaction, oxidation reaction, reductive reaction, and so on. The recent advances of PEG applied in orgainc synthesis are reviewed.
Key words: polyethylene glycol (PEG), green solvent, catalyst carrier, organic synthesis
