Research Interests

Metal-catalyzed organic reaction development and mechanistic study

Research in the Shaughnessy group focuses on organometallic chemistry. One of the most interesting and important applications of organometallic complexes is as catalysts in organic synthesis. Therefore our efforts are focused on understanding organometallic reaction mechanisms that are relevant to important catalytic systems. By understanding the mechanism by which organometallic species catalyze important transformations, we can develop new or improved synthetic methodologies. Much of our research focuses on the use of alternative solvents in catalysis in an effort to develop more environmentally benign catalytic processes. Current research efforts in the group include the following:

  • Development of novel ligands for aqueous-phase catalysis: Water is an attractive environmentally benign solvent. We are interested in designing new ligands that will provide efficient, water-soluble catalysts for organic reactions. We have developed a family of water-soluble phosphines that provide efficient catalysts for palladium-catalyzed cross-coupling reactions in aqueous-solvents. Current efforts are focused at understanding the coordination chemistry of these ligands and designing the next generation of ligands that will provide improved catalyst performance.
  • Structure-activity relationships for ligands: The Shaughnessy group has a long-standing interest in understanding how steric and electronic properties of ligands affect catalyst performance.  In collaboration with computational chemists, we try to understand how ligand design can be used to design more efficient catalyst systems.

Students in the Shaughnessy group gain experience in a wide range of synthetic techniques for organic and organometallic synthesis as well as experience with a variety of spectroscopic techniques (i.e., NMR, IR, UV/Visible, and Mass spectroscopy, as well as X-ray crystallography).
