This federal Project Grant award from the National Science Foundation's Division of Chemistry under the Mathematical and Physical Sciences (CFDA 47.049) program provides $258,403 to the University of Delaware to study the electronic structures and reactivities of four-coordinate iron- and cobalt-carbene complexes for application in catalytic carbene transfer reactions. The key objectives are to establish how changes in molecular structure and coordination geometry influence the electronic properties of these metal-carbene species, connect differences in electronic structure to catalytic reactivity, and investigate the potential of four-coordinate iron-carbene complexes for olefin metathesis reactions. This work aims to develop design principles for using earth-abundant metals like iron and cobalt as replacements for precious metal catalysts, with potential to improve the sustainability and cost-effectiveness of fine chemical production processes in the United States. The award period runs from March 15, 2025 through February 28, 2026. No sub-awards are planned under this grant.
