以KF─Al_2O_3为固碱相转移催化合成环丙烷羧酸酯

Synthesis of Cyclopropane Carboxylates through Phase Transfer Catalysis with Potassium Fluoride Coated Alumina as A Solid Base

以氟化钾浸渍的氧化铝为固碱，在相转移催化条件下合成了环丙烷羧酸酯２ａ～ｄ，探讨了该反应的机理。

Cyclopropane carboxylates 2a～d were synthesized with potassiumfluoride coated alumina as a strong base and under solid-liquid phase transfer catalysis.A discussion of the reaction mechanism was given in this paper.
