Under mild reaction conditions, the C=C double bond in isatin-derived electron-deficient alkenes has been exclusively reduced in the presence of alkylphosphanes and water to afford the corresponding reduction products in good to excellent yields. A plausible mechanism is proposed on the basis of deuterium-labeling experiments.
在温和的反应条件下,靛红衍生的缺电子烯烃中的 C=C 双键在烷基膦和水的存在下被完全还原,以良好到极好的收率提供相应的还原产物。在氘标记实验的基础上提出了一种合理的机制。
