Mizoroki-Heck macrocyclization reactions are carried out at 1 M concentration with ligand-free Pd cluster catalysts either in solution or supported on solids. Mechanistic studies unveil the essential role of the fluxional Pd cluster to accommodate, at the same time, the reacting groups, to give the intramolecular vs. the intermolecular coupling reaction at this high concentration, enabling (in-flow)
Mizoroki-Heck 大环化反应在 1 M 浓度下使用溶液或固体负载的无配体 Pd 簇催化剂进行。机理研究揭示了流动钯簇的重要作用,同时容纳反应基团,在这种高浓度下进行分子内与分子间偶联反应,从而实现(流动)固体催化大环化反应。
