Russell P. Hughes

Russell P. Hughes (born December 23, 1946) an American/British chemist, is the Frank R. Mori Professor Emeritus and research professor in the Department of Chemistry at Dartmouth College. His research interests are in organometallic chemistry, with emphasis on the chemistry of transition metal complexes interacting with fluorocarbons. His research group's work in this area led to several creative syntheses of complexes of transition metal and perfluorinated hydrocarbon fragments.

Education Hughes was born on December 23, 1946, in Denbigh, Wales, the son of Elliot and Joan (Profit) Hughes. He earned his B.Sc. at the University of Manchester Institute of Science and Technology, and his Ph.D. at the University of Toronto under John Powell. He held postdoctoral fellowships at the University of Bristol in Michael Green's laboratory and at McGill University with John Harrod.

Research career Hughes began his independent scientific career as an assistant professor at Dartmouth College in 1976. He was promoted to associate professor in 1982, and Professor in 1986. He chaired the department of Chemistry from 1991 to 1994. In 1999, he was appointed to be the Inaugural Frank R. Mori Professor in the Arts & Sciences. His research has centered on organometallic chemistry, with focus on the chemistry of transition metal complexes interacting with fluorocarbons and the organometallic chemistry of small organic rings. One striking difference in the coordination complexes of OFCOT is that their thermal stability and resistance to dynamic rearrangements in binding geometry (diminished fluxional character) compared to COT analogs. Ruthenocene and its perfluorocyclopentadienyl analog were compared. It was observed that the C5F5 interaction with Ru results in a shorter distance between this ring and Ru, compared to the hydrocarbon analog.

Perfluorocarbene Complexes In 2005, through an inner-sphere reduction reaction of perfluoroalkyl ligands Hughes and coworkers provided a novel and useful route to difluorocarbene and perfluoroalkylidene complexes. This was followed in 2007 by the synthesis of the first, and so far, the only, example of a carbene ligand bearing two strongly electron withdrawing perfluoroalkyl groups.
