CURRENT PROJECTS

 

Hydrogen Atom Transfer: 

Jeff is interested in biologically relevant proton-coupled electron transfer (PCET) reactions.  We use small molecule model systems to understand PCET reactions of bis(histidine) ligated heme cofactors, which are of emerging biological importance (e.g. ascorbate).

Rebecca is studying the effects of protons on the redox properties and surface characterization of charged ZnO quantum dots.

Tristan  is studying CPET in phenol-base model compounds and is looking at CPET with multiple protons transferred through hydrogen-bonded chains in these compounds.

Shoshanna is studying the mechanism of water oxidation using dicopper compounds. 

Mauricio studies concerted proton-electron transfer (CPET) in the oxidation of small molecule phenol-base compounds where intermolecular electron transfer is coupled to intramolecular proton transfer. He is especially interested in fast rates in the high driving force region.  Also of interest is the effect of the proton transfer on the kinetics and thermodynamics of the overall CPET process.  Our goal is to explore and understand parameters that influence the CPET reaction. Other research involves multielectron and multiproton transfer in ruthenium complexes.

Strong Oxidants and Catalysis:

Lisa is investigating the synthesis and reactivity of aqueous and non-aqueous iridium (III/V) porphyrin and indenyl complexes.

Mike's research is focused on the development of a catalytic cycle for oligomerization of methane.  1 e- oxidants react with PdMe₂^tBu₂bipy in acetone to generate ethane and [Pd(Me)(acetone)^tBu₂bipy]⁺.  We have recently uncovered mechanistic details of this oxidatively induced reductive elimination and are working on a method to activate methane and complete the catalytic cycle.

David is studying the oxidation of alkanes by osmium tetroxide.

Sophia is exploring the reactivity of frustrated Lewis acid-base pairs with CO₂.
