丙二酸二乙酯丙烯基化合成法的改进

丙二酸二乙酯丙烯基化合成法的改进 A MODIFIED METHOD FOR ALLYLATION OF DIETHYL MALONATE SYNTHESIS 刘惠英 Liu Huiying 1 first-author Department of Chemistry Wuhan University Department of Chemistry Wuhan University Department of Chemistry, Wuhan University Department of Chemistry, Wuhan University 本文报导了丙二酸二乙酯丙烯基化的一种安全、简便的方法。本法用碳酸钾代替氢化钠、用丙酮代替四氢呋喃。与此同时,应用红外光谱法跟踪化学反应过程,了解化学反应进行的深度。本法具有实用价值。 In this paper, a easy and safe method about synthesis of diethyl diallyl malonate and diethyl allyl malonate is presented. The method uses both potassium carbonate instead of sadium hydride and acetone instead of tetrahydrofuran as reagents. The absorption peaks of infrared spectrum(1640cm -1 , 1200—1140cm -1 are applied to the chemical reaction tracking to obtain results in this synthesis method. 丙二酸二乙酯 丙烯基化反应 红外光谱法 Diethyl malonate Allylation reaction Infrared spectrum method 1988-02-01 2021-04-01 2
