Conjugate addition of pinacolato(allyl)boron to benzylidenealkylidene ketones is remarkably facile when catalyzed by Ni(0) and Pd(0) complexes. Simple enones are inert to the reaction conditions, suggesting a significant activating effect by the auxiliary benzylidene unit. A comparison of different catalysts and substrates is provided, as is a mechanistic rationale, and an example of asymmetric catalysis
当由 Ni(0) 和 Pd(0) 配合物催化时,频哪醇(烯丙基)硼与亚苄基亚烷基酮的共轭加成非常容易。简单的烯酮对反应条件是惰性的,表明辅助亚苄基单元具有显着的活化作用。提供了不同催化剂和底物的比较,以及机械原理和不对称催化的示例。
