报道了烯丙基芳基化合物的电化学氧化酯化方法, 通过同时活化苄位烯丙位的C—H和C—C键, 合成了一系列苯甲酸酯类化合物. 本反应展现了良好的化学选择性, 优先在苄位烯丙位发生氧化, 而其它的苄位C—H键则保持稳定. 该反应在中性条件下进行, 无需酸碱添加剂, 可以适用叔醇酯的构建, 同时避免酯和醇存在下的转移酯化副反应.

关键词: 烯丙基, 苄基, 电化学, 酯化

An electrochemical C—H and C—C bond esterification reaction with allyl arene as a substrate is reported. This oxidation takes place selectively at the benzylallyl C—H site instead of other benzylic C—H groups. Since the reaction does not require acid/base catalysis for esterification, tertiary alcohol is suitable for the synthesis of the corresponding ester. In addition, side reactions such as transesterification can be avoided with this neutral protocol.

Key words: allyl, benzyl, electrochemistry, esterification
