摘　　要：研究了KF-Al2O3催化下芳醛和氰基乙酸酯在醇介质中的反应,发现了溶剂醇和产物2-氰基-3-芳基丙烯酸酯随后发生酯交换反应.还研究了不同的芳醛、氰基乙酸酯和醇在KF-Al2O3催化下的该酯交换反应.该方法为2-氰基-3-芳基丙烯酸酯的合成提供了新的方法.The reactions of aromatic aldehyde and cyanoacetate in alcohol catalyzed by KF-Al2O3 are studied in this paper. It is interesting that the subsequent transesterification is carried out between the products of 2-cyano-3-aryl-1-acrylate and alcohol. The different aromatic aldehydes, different cyanoacetates and different alcohols are further discussed in the KF-Al2O3 catalyzed transesterification. This transesterification supplies a new procedure for the synthesis of 2-cyano-3-aryl-1-acrylate.
