An efficient, binaphthyl‐backbone‐stabilized palladium nanoparticles (Pd‐BNP) catalyst for the 1,4‐addition of aryl halides to enones has been developed. The scope of the reaction has been studied with various substituted and sterically hindered aryl halides and enones to afford the conjugate addition products in good to excellent yields. The catalyst has been recovered and reused up to five times without any appreciable change in particle size or reactivity.

稳定和可重复使用的钯纳米粒子催化芳基碘化物与烯酮的共轭加成：还原性Heck产品的途径

已开发出一种高效的双萘基骨架稳定的钯纳米粒子（Pd-BNP）催化剂，用于将1,4-芳基卤化物加成烯酮。已经用各种取代的和空间受阻的芳基卤化物和烯酮研究了反应的范围，从而以良好或优异的产率提供了共轭加成产物。催化剂已被回收并重复使用了五次，而粒径或反应性没有明显变化。
