A Brønsted acid enabled nickel‐catalyzed hydroalkenylation of aldehydes and styrene derivatives has been developed. The Brønsted acid acts as a proton shuttle to transfer a proton from the alkene to the aldehyde, thereby leading to an economical and byproduct‐free coupling. A series of synthetically useful allylic alcohols were obtained through one‐step reactions from readily available styrene derivatives and aliphatic aldehydes in up to 88 % yield and with high linear selectivity.

Brønsted酸使苯乙烯及其衍生物对醛进行镍催化的加氢烯基化反应

已经开发出布朗斯台德酸使醛和苯乙烯衍生物的镍催化加氢烯基化反应。布朗斯台德酸起质子穿梭的作用，将质子从烯烃转移到醛中，从而实现了经济和无副产物的偶联。通过一步反应从容易获得的苯乙烯衍生物和脂肪醛中一步获得了一系列合成有用的烯丙醇，收率高达88％，并且具有很高的线性选择性。
