Transition Metal Complexes with <i>N</i>-Heterocyclic Vinylidene Ligands

Transition metal complexes with N-heterocyclic vinylidene ligands can be obtained by combining N-heterocyclic diazoolefins with suitable metal precursors. The vinylidene ligands can act as potent C-donor ligands, allowing for the stabilization of electron-deficient and low-coordinate metal complexes.
