Abstract:

A base?catalyzed 1,6?conjugate addition of p?QMs for the preparation of diaryl methyl ethers (thioether) has been developed with 37% to 95% yields, which realized the solvolysis reaction between p?QMs and alcohol (thiophenol) under the catalysis of 20% NaOH. The method features easy operation, mild condition and good functional tolerance. A gram scale experiment was examined in 80% yield, which provides possibility for potential application and transformation in later stage.

Key words: Base catalyzed, p?QMs, 1,6?Conjugate addition, Alcohol, Diaryl methyl ethers

摘要:

在摩尔分数为20%的氢氧化钠的催化作用下,实现了对亚甲基苯醌(p?QMs)与醇(或硫酚)的溶剂解反应,即p?QMs的1,6?共轭加成反应,以37%~95%的产率制备了一系列二芳基甲基(硫)醚类化合物。结果表明,该反应具有操作简便、反应条件温和高效、官能团耐受性良好等特点;该方法易于放大,能以80%的产率得到二芳基甲基乙基醚,为后期的潜在应用与转化提供了可能。
