W. Dean Harman is the Willilam R. Kenan, Jr. Professor of Chemistry in the Department of Chemistry at the University of Virginia, where he conducts research at the intersection of inorganic and organic chemistry. His work focuses on the activation and transformation of aromatic compounds using transition metal complexes.
His educational background includes a B.S. and Ph.D. from Stanford University, followed by a Research Associate position at the same institution. This strong foundation has enabled his long-standing research program in organometallic chemistry.
- B.S., Stanford University, 1983
- Ph.D., Stanford University, 1987
- Research Associate, Stanford University, 1988–1989
Harman's research centers on the dearomatization of arenes through η²-coordination to transition metals such as osmium, rhenium, molybdenum, and tungsten. Unlike traditional η⁶-coordination that activates arenes toward nucleophilic attack, η²-coordination enhances their susceptibility to electrophilic addition by backbonding into the π* orbitals. This approach enables novel synthetic pathways to complex alicyclic structures from abundant aromatic feedstocks. His group has pioneered the development of new dearomatization agents based on Group 6 metals, enabling the synthesis of highly functionalized cyclohexenes, isotopically labeled compounds, and heterocycles such as isoquinuclidines. The integration of experimental work with computational simulations further strengthens mechanistic understanding.
His recent publications reveal a consistent focus on expanding the scope and mechanistic understanding of metal-mediated arene activation. Key trends include the use of tungsten and molybdenum complexes for tandem addition and cycloaddition reactions, the synthesis of isotopologues for structural analysis, and the application of direct dynamics simulations to probe reaction equilibria. These works appear in high-impact journals such as Nature, Journal of the American Chemical Society, and Chemical Reviews, reflecting the significance of his contributions.
His scientific honors include being named the Willilam R. Kenan, Jr. Professor of Chemistry, a distinguished endowed professorship at the University of Virginia.

While specific names of students are not listed, Harman leads an active research group (the Harman Lab), supervises graduate researchers, and publishes regularly with junior co-authors, indicating a strong mentoring role. Although grant details are not mentioned, sustained research output and publication in top journals suggest continuous external funding. The Harman Lab is an interdisciplinary team focused on pushing the boundaries of synthetic methodology using transition metal chemistry.
The lab maintains a digital presence via Google Sites and engages in dissemination through seminars and publications. Collaborations with computational chemists (e.g., D. H. Ess) highlight the integrative nature of the research. Future directions likely include expanding the library of η²-coordination agents, exploring applications in bioactive molecule synthesis, and further elucidating reaction dynamics through simulation.
