Abstract

Stuck on Ru: The lability of the N₂ ligand is thought to limit the efficacy of late-transition-metal complexes for the catalytic activation of N₂. However, complex 1 is found to bind N₂ with unprecedented strength. This species resists displacement of N₂ by CO at room temperature, while computational and experimental data suggest that the Ru-N₂ binding is stronger than the Ru-IMes binding. IMes=N,N'-bis(mesityl)imidazol-2-ylidene. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
