In tandem catalytic systems, controlling the reaction steps and side reactions is extremely challenging. Here, we demonstrate a nanoreactor platform comprising magnetic- and plasmonic-coupled catalytic modules that synchronizes reaction steps at unconnected neighboring reaction sites via decoupled nanolocalized energy harvested using distinct antennae reactors while minimizing the interconflicting effects. As was desired, the course of the reaction and product yields can be controlled by a convenient remote operation of alternating magnetic field (AMF) and near-infrared light (NIR). Following this strategy, a tandem reaction involving [Pd]-catalyzed Suzuki–Miyaura C–C cross-coupling and [Pt]-catalyzed aerobic alcohol oxidation enabled an excellent yield of cinnamaldehyde (ca. 95%) by overcoming the risk of side reactions. The customization scope for using different catalytic metals (Pt, Pd, Ru, and Rh) with in situ control over product release through remotely operable benign energy sources opens avenues for designing diverse catalytic schemes for targeted applications.

用于分区正交串联催化的磁-等离子体多模空心纳米反应器

在串联催化系统中,控制反应步骤和副反应极具挑战性。在这里,我们展示了一个包含磁性和等离子体耦合催化模块的纳米反应器平台,该平台通过使用不同的天线反应器收集的解耦的纳米局部化能量同步未连接的相邻反应位点的反应步骤,同时最大限度地减少相互冲突的影响。正如所期望的那样,反应过程和产物产率可以通过交变磁场 (AMF) 和近红外光 (NIR) 的方便远程操作来控制。遵循这一策略,涉及[Pd]催化的Suzuki-Miyaura C-C交叉偶联和[Pt]催化的有氧醇氧化的串联反应通过克服副反应的风险实现了肉桂醛的优异收率(约95%) .通过可远程操作的良性能源对产品释放进行原位控制,为针对目标应用设计不同的催化方案开辟了道路。
