(eta-6-2-bromo-1,1'-biphenyl)tricarbonylchromium

My research interests are in organometallic chemistry.  This area is at the interface between organic chemistry and inorganic chemistry, and involves molecules and reactions not otherwise available in traditional organic or inorganic chemistry.  My research group synthesizes new organometallic molecules and uses infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy, as well as X-ray crystallography, to study their structures and reactions.  Most importantly we are interested in novel rearrangement mechanisms that may be important in catalysis, including hydroxycarbene-acyl hydride equilibria and arene-arene haptotropic rearrangements.
