Ligand-mediated multielectron redox reactions at first-row transition metal centers


Jake D. Soper,, School of Chemistry and Biochemistry, Georgia Institute of Technology, Atlanta, GA 30332-0400
Multielectron redox chemistry forms the basis of most selective bond-making and bond-breaking reactions. We are pursuing the development of new molecular catalysts that utilize redox-active quinoid ligands as electron reservoirs for novel multielectron transformations of small-molecule substrates. Towards this goal, new four- and five-coordinate complexes based on square planar manganese and cobalt cores with catecholate and amidophenolate ligands have been prepared and characterized. This lecture will present exploratory and mechanistic studies of stoichiometric and catalytic redox transformations which are dependent on the ability of the non-innocent ligands to impart a multielectron capacity to the low-valent, first-row transition metal centers.
