Research and publishing
Dr. Czerwinski’s research interests are in organometallic chemistry, which is an area at the interface between organic chemistry and inorganic chemistry.
His research group synthesizes new organometallic molecules and uses infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy to study their structures and reactions. He has developed collaborations with scientists at UW-Madison and Moscow State University to conduct X-ray crystallographic studies and density functional theory (DFT) calculations to study the structural and dynamic features of target molecules.
His specific interests involve the design and synthesis of molecules that exhibit rearrangements with industrial and biological applications. These include hydroxycarbene-acyl hydride equilibria, and arene-arene haptotropic rearrangements in biphenyl chromium compounds that may act as molecular switches or molecular devices. He has recently extended this work toward the synthesis of water-soluble organometallic compounds that may have medicinal applications.
