Research Interests:
World-wide activity in the investigation
of transition metal-catalyzed reactions continues to be high in both industrial
and academic circles. Our research in this field reaches for an understanding
of the fundamental molecular interactions between metal complexes and small
molecule substrates such as CO, NO, unsaturated hydrocarbons, and carbohydrates.
We are now looking at metal complex-large molecule binding as well.
Very recently we have addressed the subject of aqueous
organometallic chemistry. These efforts have allowed us to look at catalytically-relevant
steps under more benign aqueous conditions and to address the interactions
between electrophilic metal centers and water-soluble ions. In addition,
we are able to study how biologically important species (including amino
acids and DNA) interact with reactive organometallic centers. As inorganic
chemists we utilize a wide variety of physical techniques supported in
the department, including X-ray diffraction, NMR and EPR spectroscopy,
vibrational spectroscopy, and mass spectrometry. Our studies often begin
as synthetic projects and develop into comprehensive investigations of
chemical structure, equilibrium, and reaction mechanisms.
