متن کاملOxygen isotope effects as structural and mechanistic probes in inorganic oxidation chemistry.
Oxidative transformations using molecular oxygen are widespread in nature but remain a major challenge in chemical synthesis. Limited mechanistic understanding presents the main obstacle to exploiting O(2) in "bioinspired" industrial processes. Isotopic methods are presently being applied to characterize reactions of natural abundance O(2) including its coordination to reduced transition metals...
متن کاملTransition metal speciation in the cell: insights from the chemistry of metal ion receptors.
The essential transition metal ions are avidly accumulated by cells, yet they have two faces: They are put to use as required cofactors, but they also can catalyze cytotoxic reactions. Several families of proteins are emerging that control the activity of intracellular metal ions and help confine them to vital roles. These include integral transmembrane transporters, metalloregulatory sensors, ...
متن کاملExcited-state mixed valence in transition metal complexes.
Mixed valence in the lowest-energy metal-to-ligand charge-transfer excited state of di-(4-acetylpyridine)tetraammineruthenium(II) complexes is defined and analyzed. The excited state has two interchangeably equivalent ligands with different oxidation states. The electronic absorption band energies, selection rules, and bandwidths are analyzed quantitatively in terms of the signs and orientation...
