通过羰基- 14 C 动力学同位素效应、取代基效应以及同位素加扰和探针实验,详细研究了不稳定叶立德与苯甲醛和二苯甲酮的 Wittig 反应。与二苯甲酮的反应在无锂和含盐条件下都产生了相当大的碳同位素效应和哈米特 p 值。相比之下,它们与苯甲醛的反应非常小。烯酮异构化和脱卤探针实验表明不稳定的叶立德有足够的能力将电子转移给苯甲醛和二苯甲酮

Abstract Ketones react with aromatic aldehydes via a tandem Aldol-Grob reaction sequence. The reaction, initiated by borontrifluoride, produces a carboxylicacid fragment and can serve as an alternative to the Baeyer-Villiger reaction.
