This report describes a nickel‐catalyzed allylic substitution process of simple alkenes whereby an important structural motif, a 1,4‐diene, was prepared. The key to success is the use of an appropriate nickel–phosphine complex and a stoichiometric amount of silyl triflate. Reactions of 1‐alkyl‐substituted alkenes consistently provided 1,1‐disubstituted alkenes with high selectivity. Insight into the
该报告描述了镍催化简单烯烃的烯丙基取代过程,由此制备了重要的结构基序,即 1,4-二烯。成功的关键是使用适当的镍-膦络合物和化学计量的三氟甲磺酸硅酯。1-烷基取代的烯烃的反应始终以高选择性提供 1,1-二取代的烯烃。还记录了对反应机制的深入了解以及所开发的催化过程的各种应用。
