"Strong C-H and C-C Bond Cleavage Reactions
using Homogeneous Transition Metal Complexes"
Presented by William D. Jones, University of Rochester
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 activation of fluoroaromatic C-H bonds will be presented. Extensions to C-C activation at nickel will also be made, demonstrating critical factors involved in C-C cleavage.
