相转移催化法合成醚

Preparation of Ethers Through Phase Transfer Catalysis

本文在文献的基础上,对聚乙二醇作相转移催化剂合成醚的反应进行了研究。以聚乙二醇为相转移催化剂合成醚的反应,多数是在固-液相条件下进行,液-液相条件仅见于碘甲烷的反应。对于一些活泼的氯代烃,例如2,4-二硝基氯苯同亲核性较强的酚类采用液-液相转移催化法就能得到满意的结果。

Twenty-two ethers have been synthesized by means of liquid-liquid and solid-liquid phase transfer catalysis.In comparison with original Williamson's method,the present procedure has the advantages of high yield and simplicity in operation.
