A method for increasing the rate of phosphine oxide reduction, preferably during a Wittig reaction comprising use of an acid additive is provided. A room temperature catalytic Wittig reaction (CWR) the rate of reduction of the phosphine oxide is increased due to the addition of the acid additive is described. Furthermore, the extension of the CWR to semi-stabilized and non-stabilized ylides has been accomplished by utilization of a masked base and/or ylide-tuning.
提供了一种增加膦氧化物还原速率的方法,特别是在威特希格反应中使用酸添加剂。描述了室温催化威特希格反应(CWR),由于添加酸添加剂,膦氧化物的还原速率增加。此外,通过利用掩蔽碱和/或易化物调节,已经实现了CWR的扩展到半稳定和非稳定的易化物。
