Application of first-row transition metal complexes bearing 1,2,3-triazolylidene ligands in catalysis and beyond

Abstract

Triazole-derived N-heterocyclic carbenes, available via click reactions, are versatile ligands for first-row transition metals, leading to complexes with attractive photochemical properties and catalytic activity, some defining the state-of-the-art.

Using PMHS for Catalytic Hydrosilylation with Dimeric Iron Complexes Featuring Mesoionic Carbene Ligands

“…We have been exploring the use of mesoionic triazole-derived carbene ligands for transition-metal complexes to facilitate bond activation catalysis. − An intriguing aspect of this ligand class is the strong donor properties, together with a potential to adopt either a formally netural carbenic or a zwitterionic ylid-type resonance structure with a formally carbanionic donor site. These properties have shown to impart generally high catalytic activity to the bonded transition metal .…”
