The combination of supported ionic liquids and immobilized NHC–Pd–RuPhos led to active and more stable systems for the Negishi reaction under continuous flow conditions than those solely based on NHC–Pd–RuPhos. The fine tuning of the NHC–Pd catalyst and the SILLPs is a key factor for the optimization of the release and catch mechanism leading to a catalytic system easily recoverable and reusable for a large number of catalytic cycles enhancing the long-term catalytic performance.

在流动条件下,Negishi反应的负载型离子液体样相与固定化钯N-杂环卡宾-膦配合物之间的协同作用。

与仅基于NHC-Pd-RuPhos的离子液体相比,负载的离子液体和固定化的NHC-Pd-RuPhos的组合在连续流动条件下为Negishi反应提供了活性和稳定的系统。NHC-Pd催化剂和SILLPs的微调是优化释放和捕获机理的关键因素,从而使催化体系易于回收和重复使用,可用于大量催化循环,从而提高了长期催化性能。
