  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.

  提供了一种增加磷氧化物还原速率的方法，尤其是在Wittig反应中，该方法包括使用酸性添加剂。描述了一种室温催化的Wittig反应（CWR），由于添加了酸性添加剂，磷氧化物还原的速率得到了提高。此外，通过利用掩蔽碱和/或调节基团，CWR已成功扩展到半稳定和不稳定的亚磷酰化物。
