“Developing Small-Ringed Macrocyclic Tetracarbene Ligands for Catalytic Systems”
Abstract:
Despite the numerous advances in homogeneous catalysis that have been achieved through the use of N-heterocyclic carbenes (NHCs) as auxiliary ligands, very few macrocyclic polydentate carbenes have been synthesized. Our group has synthesized a new ligand platform based on small-ringed (16 or 18 atoms) macrocyclic tetraimidazoliums as tetra-NHC precursors. These small-ringed tetracarbene macrocycles form novel and reactive complexes on group 6, 7, 8, 9, 10, and 11 metals. Numerous novel tetracarbene complexes have been characterized by spectroscopic methods and X-ray crystallography, which demonstrates that the four carbenes bind to the metal in an equatorial configuration.
BIO:
David Jenkins completed his B.A. in chemistry from Cornell University in 2000, where he conducted research with Prof. Héctor Abruña on the synthesis and electrochemistry of phenanthroline-based copper complexes. He received his Ph.D. from the California Institute of Technology in 2005, under the direction of Prof. Jonas Peters, for his study of low-spin pseudo-tetrahedral cobalt(II) complexes. While at Caltech, Dr. Jenkins synthesized the first cobalt-imide complex. Dr. Jenkins then joined the laboratory of Prof. Jeffrey Long as a Miller Institute for Basic Research postdoctoral fellow at the University of California, Berkeley. His research at U.C. Berkeley focused on the development of pentadentate capping ligands for utilization in single-molecule magnets and other magnetic materials. Dr. Jenkins joined the faculty of the University of Tennessee in 2008.
