Gibbs Acceptance Address: “Alkane Metathesis: A Route to Tomorrow’s Fuels?”
There are now numerous transition metal-based systems known that will activate carbon-hydrogen bonds of alkanes via oxidative addition reactions. Only a few such reactions have been incorporated into viable, efficient catalytic cycles. This presentation will focus on the use of pincer iridium complexes in catalytic transformations in which C-H bond activation is the key step. These processes will include: 1. intermolecular hydrogen transfer reactions as a method for introducing carbon-carbon double bonds into alkanes and 2. coupling such reactions with alkene metathesis which provides a method for converting linear alkanes to alkanes of higher and lower carbon number. This alkane metathesis reaction can potentially be used for converting alkanes generated via the Fischer-Tropsch process to alkanes in the diesel range, thus providing increased efficiency for producing transportation fuels from coal and biomass. Homogeneous and supported catalysts will be described and mechanistic aspects of these processes will be highlighted.
Maurice Brookhart (b. 1942) grew up in the mountains of western Maryland and attended Johns Hopkins University in Baltimore where he received an A.B. degree in chemistry in 1964. He carried out his doctoral work in physical organic chemistry at UCLA under the direction of Saul Winstein. After finishing the Ph.D. degree in 1968, he spent six months as a National Science Foundation postdoctoral fellow at UCLA with Winstein and Frank Anet, followed by a year of study at Southampton University as a NATO postdoctoral fellow. Brookhart joined the University of North Carolina faculty in 1969 and is currently a William R. Kenan, Jr. professor of chemistry. He has spent research leaves at Univ. of Rennes (1981), Oxford (1982-83), UC-Berkeley, (Fall, 1996), Seville (Spring, 1997), University of Marburg (Spring, 2001) and the Max Planck Institute, Muelheim (Spring, 2003). Brookhart served as associate editor of Organometallics (1990-96) and received the 1992 American Chemical Society(ACS) Award in Organometallic Chemistry, a 1994 ACS Cope Scholar Award and the 2003 ACS Award in Polymer Chemistry. He was elected to the American Academy of Arts and Sciences in 1996 and the National Academy of Sciences in 2001 and received the North Carolina Award in Science in 2008.
Brookhart’s research interests span mechanistic, synthetic, and structural organometallic chemistry. Most recently efforts have focused on the development and mechanistic understanding of late transition metal complexes for olefin polymerizations and employing carbon-hydrogen bond activation processes in catalytic transformations of small molecules.
