Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions of liquid, unbiased dibromoarenes under mechanochemical conditions selectively afford the monoarylated products. The lower reactivity of the crystalline monoarylated products rela-tive to the liquid starting materials should be attributed predom-inantly to the low diffusion efficiency of the former in the re-action mixture, which results in

溴芳烃的 Suzuki-Miyaura 交叉偶联反应选择性地提供单芳基化产物。结晶单芳基化产物相对于液体原料的较低反应性主要归因于前者在反应混合物中的低扩散效率,这导致选择性单芳基化。本研究揭示了一种新方法,该方法使用固体中的原位相变来设计通过传统的基于溶液的合成难以实现的选择性有机转化。
