This three-year project grant from the National Science Foundation's Division of Chemistry, under the Mathematical and Physical Sciences program (CFDA 47.049), provides $442,816 to Portland State University to study the intersection of chemical structure, bonding models, and reactivity of hypervalent organohalogens through September 2025. Professors David Stuart and Theresa McCormick will employ combined experimental and theoretical approaches to gain new insights into halogen bonding and the bifunctional character of diaryliodonium salts. Specifically, they will focus on orbital interactions in halogen bond donors, the bifunctional properties of diarylhalonium salts in noncovalent interactions, and reactions of diarylhaloniums with pronucleophiles based on bifunctional activation. The research aims to advance new synthetic methods and catalysis for organic synthesis by correlating bonding models with structure and thermodynamic/kinetic reactivity. Graduate and undergraduate students will participate in the research, furthering the training of the next generation of scientists.
