The power of organocatalysts featuring two distinct catalytic sites in one molecule was illustrated in the ROCOP of epoxides with anhydride, giving excellent selectivity and activity. A chain tug-of-war mechanistic pathway is proposed to rationalize the simultaneous enhancement in monomer activation and nucleophilic attack, thus giving rise to outstanding catalytic performance.
在一个分子中具有两个不同催化位点的有机催化剂的能力在环氧化物与酸酐的 ROCOP 中得到了说明,具有出色的选择性和活性。提出了一种链式拔河机制途径,以合理化同时增强单体活化和亲核攻击,从而产生出色的催化性能。
