Added Complexity!—Mechanistic Aspects of Heterobimetallic Complexes for Application in Homogeneous Catalysis

Molecules, Journal Year: 2023, Volume and Issue: 28(10), P. 4233 - 4233

Published: May 22, 2023

Inspired by multimetallic assemblies and their role in enzyme catalysis, chemists have developed a plethora of heterobimetallic complexes for application homogeneous catalysis. Starting with small σ-donating π-accepting ligands, such as N-heterocyclic carbene carbonyl more complex systems been over the past two decades. These can show significant increase catalytic activity compared monometallic counterparts. This be attributed to new reaction pathways enabled presence second metal center active catalyst. review focuses on mechanistic aspects Depending type interaction substrates, subdivided into four classes. Each these classes is illustrated multiple examples, showcasing versatility both, types interactions possible, reactions accessible.

This review summarizes developments in the synthesis and catalytic applications of those heterobimetallic carbene complexes which at least two different metals are bound to same ligand by one M-C(carbene) bond each. Several new synthetic methods for such yielding well-defined thoroughly characterized compounds presented. The were found be catalytically active several (most often tandem) reactions. In certain cases, incorporation into imidazole- or triazol-based NHC-carbene complex resulted substantially higher activity compared either its homobimetallic analogs mixtures comparable mononuclear fragments containing independently. is a clear demonstration advantageous metal–metal cooperation within catalyst. Opposite examples also discussed, where proved inferior relation homonuclear fragments.
