Allylic alcohols, aldehydes, and triphenylphosphine participate in a one-pot process catalyzed by palladium, which is formally equivalent to the Wittig olefinization. It can be applied to both aliphatic and aromatic aldehydes. The resulting olefins which appear as mixtures of stereoisomers were fully hydrogenated. Two different mechanisms can account for the observed results.

钯的催化下参与了一个单锅过程,该过程在形式上等同于维蒂希烯烃化。它既可用于脂肪醛,也可用于芳香醛。生成的烯烃以立体异构体混合物的形式出现,并被完全氢化。有两种不同的机制可以解释观察到的结果。
