Homoleptic ruthenium complexes [Ru(Ln)2]2+ bearing unsymmetric pyridine-based bis N-heterocyclic carbene (NHC) pincer ligands are synthesized and structurally characterized. These complexes feature the coexistence of a five-membered and a six-membered ruthenacycle within the same ligand framework, allowing an ideally octahedral CNHC-Ru-N Py bite angle close to 90°. In the solid state, impressive 3MLCT lifetimes of microsecond regime were detected in all of the complexes, of which [Ru(L4)2]2+, featuring four benzimidazol-2-ylidene donors, exhibited the longest values. Electronic properties of all of the ruthenium complexes are investigated by cyclic voltammetry and spectroscopic techniques. Density functional theory results were used to support the experimental observations.
Copper(II)-hydroperoxo complex induced oxidative N-dealkylation chemistry

, p. 6720 - 6721 (2007)
A significant oxidative N-demethylation reaction occurs from a hydroperoxo-copper(II) species when formed within a tripodal tetradentate ligand framework possessing a pendant dimethylamine substrate. This mimics the monoxygenase activity occurring in the copper enzyme PHM. Observation of a product-based alkoxide-Cu intermediate and determination of a reaction kinetic isotope effect (kH/kD(intra) ~ 2.3) by studying the ligand-N(CH3)(CD3) substrate provide further insights. The mononuclear CuII(-OOH) entity or species derived from this can promote biomimetic reactivity and thus requires further attention in biological or synthetic mechanistic studies. Copyright
