通过电化学介导羧酸和醇反应合成了一系列酯类化合物. 该策略通过温和绿色的电化学合成方式进行, 反应在室温下即可发生, 无需惰性气体保护, 过程中也无需使用强酸和金属催化剂等进行辅助催化. 反应在无隔膜电解槽中以恒流模式进行, 以较高的收率生成酯化产物. 相比有机试剂促进的酯化反应, 该方案不残留需柱层析分离的副产物, 可适用难于反应的叔丁醇.

A series of esters were prepared by electrochemical synthesis of carboxylic acids with alcohols. This protocol can be carried out at room temperature without inert atmosphere, strong acids or metal catalysts, etc. The esterification reaction processes in an undivided electrolytic cell with constant current mode and the esterification products are generated in good yields. Compared with esterification promoted by organic reagents, this protocol avoids the byproducts which have to be separated by column chromatography and successful for tertiary alcohol which is generally difficult to undergo esterification directly, providing a new access to the esterification of carboxylic acids and alcohols.

Key words: electrochemical mediation, esterification reaction, electromechanical synthesis
