    DOI:10.1002/1615-4169(200206)344:3/4<370::aid-adsc370>3.0.co;2-3
    日期:2002.6
    Alkylation reactions of active methylene compounds, alcohols and phenols with alkyl halides in aqueous NaOH solution can be carried out without the need for any added organic solvents in most cases. The water-soluble calix[n]arenes, which contain trimethylammoniomethyl groups on the upper rim, were used as inverse phase-transfer catalysts, resulting in the corresponding alkylated products in good to
    在大多数情况下,无需任何添加的有机溶剂即可在 NaOH 水溶液中进行活性亚甲基化合物、醇和酚与烷基卤化物的烷基化反应。水溶性杯[n]芳烃在上缘含有三甲基氨甲基,用作反相转移催化剂,得到相应的烷基化产物,产率从良好到高产率。讨论了该方法在水性双相烷基化反应中的范围和机理意义。

    日期:1969.6.1
    prepared from sodium hydroxide, n-butyl alcohol, and n-butyl chloride using excess of the alcohol as solvent in 61% yield after 14 h reaction time. However, when the excess alcohol was replaced by dimethyl sulfoxide, the yield of ether rose to 95% with 9.5 h reaction time. Other primary alkyl chlorides exhibited similar behavior to n-butyl chloride, but secondary alkyl chlorides and primary alkyl bromides
