摘要: 本文以聚乙二醇(PEG)为相转移催化剂,对Perkin反应进行了研究。实验结果表明:聚乙二醇在Perkin反应中有明显的催化作用,平均分子量为600的聚乙二醇催化效果较好;PEG-600可使Perkin反应产率提高10%以上;反应时间显著缩短;PEG-600用量1%mol左右为宜。

Abstract: Perkin reactions under phase transfer catalysis of poly(ethylene glycols)(PEG) were studied. It was shown that PIGgave a obvious catalylical effect on the reactions. PEG-600 of average molecular weight were more efficient than the others examined. The yields of Perkin reactions with PEG-600 were higher than that without it by 10%. Morever, the reaction time was shortened remarkably. Appropriate amount of PEGused in the reactions was ca. 1% (mole).
