Dow Seminar in Inorganic Chemistry: Why Do Weaker Bonds Lead to More Stable Complexes? What is Going On?

Seminar | April 6 | 4-5 p.m. | 120 Latimer Hall

 Bill Jones, Department of Chemistry, University of Rochester

 College of Chemistry

Over the past 20 years substantial progress has been made in the understanding of the activation of C-H and other strong bonds by reactive metal complexes in low oxidation states. This talk will present an overview of the use of pentamethylcyclopentadienyl and trispyrazolylborate rhodium complexes for the determination of thermodynamic factors that influence the activation of arene and alkane C-H bonds. Insights into bond strengths, kinetic and thermodynamic selectivities, and the nature of the intermediates involved will be examined. The influence of substituent effects on the thermodynamics of bond activations will also be analyzed. Trends in the effects of ligand donor strength on C-H activation will be examined.

 Light refreshments will be served at 3:50 at The Coffee Lab, 510-643-0572
