“Metal-Metal Multiply Bonded Intermediates in Catalysis”
Abstract:
Metal-metal bonded derivatives of dirhodium tetraacetate are well-known catalysts for carbenoid and nitrenoid transformations of organic compounds. Despite the widespread use of this methodology in synthesis, few mechanistic details of the reactions are known. I will present my research group’s efforts to isolate and study reactive intermediates, dirhodium carbene and amido complexes, relevant to these important catalytic transformations, emphasizing the relationship between electronic structure, bonding, and their reactivity. Related diruthenium nitrido intermediates will also be presented, including their C–H amination reactivity and nitrogen atom transfer reactivity.
Bio:
Dr. Berry was born in Atlanta, Georgia, and grew up in Newport News, Virginia. He obtained a B.A. degree in Music Theory and Composition and a B.S. degree in Chemistry, both from Virginia Tech (2000), and a Ph.D. in inorganic chemistry from Texas A&M University (2004). Following postdoctoral work with Karl Wieghardt at the Max Planck Institute for Bioinorganic Chemistry in Mülheim an der Ruhr (Germany), he joined the Department of Chemistry at the University of Wisconsin – Madison, where he is now an Associate Professor with tenure. His research interests are centered on the synthesis, reactivity and electronic structure of coordination complexes, particularly those having paramagnetic transition metal centers or linear M=M=L structures.
