首次描述了一系列定制设计的高产率等骨架四核 Zn/4f 配位簇，这些簇在弗里德尔-克来福特烷基化中作为低催化负载量的催化剂表现出高效率。在不改变核心拓扑的情况下改变这些催化剂中的 4f 中心的可能性使我们能够通过 EPR 和 NMR 进一步确认它们的稳定性，并深入了解合理的反应机制，展示这些双金属系统作为催化剂的有用性。
A series of custom-designed, high yield, isoskeletal tetranuclear Zn/4f coordination clusters showing high efficiency as catalysts with low catalytic loadings in Friedel-Crafts alkylation are described for the first time. The possibility of altering the 4f centers in these catalysts without altering the core topology allows us to further confirm their stability via EPR and NMR, as well to gain insights into the plausible reaction mechanism, showcasing the usefulness of these bimetallic systems as catalysts.
