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。
In this paper, tetraethylammonium iodide was used as the solid-liquid phase transfer catalyst for the first time. Catalytic carbonylation of ethyl chloroacetate was carried out at normal temperature and pressure to synthesize diethyl malonate quantitatively. Various factors Effect of reaction yield.
