Heterodimerization of olefins is a reaction of enormous synthetic potential, since it has been demonstrated that excellent yields and selectivities can be achieved under exceptionally mild conditions in many cases.1,2 For example, we have recently shown that using catalysts derived from [(allyl)Ni(Br)]2 and a tertiary phosphine in combination with a silver salt, a nearly quantitative hydrovinylation
烯烃的异二聚反应是一种具有巨大合成潜力的反应,因为已经证明在许多情况下可以在异常温和的条件下实现出色的产率和选择性。 1,2 例如,我们最近表明,使用衍生自 [(烯丙基)Ni(Br)]2 和叔膦与银盐的结合,可以实现乙烯基芳烃的几乎定量的加氢乙烯基化(方程式 1)。在我们的
