本文首次以四乙基碘化铵为固-液相转移催化剂, 在常温常压下对氯乙酸乙酯进行催化羰基化反应, 定量合成了丙二酸二乙酯, 并讨论了各种因素对反应收率的影响。

关键词: 丙二酸乙二酯, 顺磁共振, 反应机理, 氯乙酸乙酯, 红外分光光度法, 相转移催化, 羰基化作用, 四乙基碘化铵, 催化剂, 气相色谱

Diethyl lalonate was synthesized in early 100% Yields using tetraeth-ylammonium iodide as phase transfer agents by catalyzed- carbonylation under moderate condi-tions, The mechanism and the factors influenced the reaction yields were studied.
