Electrochemical studies on [ R ~ ( ~ ~ B U , P ) ( C O ) ~ ] ~ have shown that upon reduction in THF it undergoes an ECE-type mechanism, a chemical reaction coupled between two electron-transfer reactions, to form a dianion. The chemical step is a geometric isomerization, producing an isomer which is more easily reduced than the parent compound. Oxidation of the dianion back to the neutral comp...

Chapter 1. Synthesis and Characterization of a Novel Class of Dicopper(I) Bis(carboxylate)-Bridged Complexes The syntheses, spectroscopic properties, crystal and molecular structures, and bonding of several dicopper(I) bis(carboxylate)-bridged complexes are described in which the bridging dicarboxylate ligand is the dianion of m-xylylenediamine bis(Kemp's triacid imide) (H2XDK, 1). A sterically...

Quercetin 2,3-dioxygenase (2,3QD) is a mononuclear copper-dependent dioxygenase which catalyzes the cleavage of the heterocyclic ring of the flavonol quercetin (5,7,3′,4′-tetrahydroxy flavonol) to produce 2-protocatechuoyl-phloroglucinol carboxylic acid and carbon monoxide. In this study, X-ray absorption spectroscopy has been used to characterize the local structural environment of the Cu2+ ce...
