Tetranuclear Zn/4f coordination clusters as highly efficient catalysts for Friedel–Crafts alkylation

Abstract

A series of custom-designed isoskeletal tetranuclear 3d/4f coordination clusters (CCs) show high efficiency as catalysts in Friedel–Crafts alkylation. 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.
