Hydrogen Atom Transfer from Carbon to Metal - Relevance of a Novel Reaction to Catalyzed Hydrocarbon Conversions

   This program seeks to carry out fundamental studies to investigate a novel type of chemical reaction that could have significant practical utility in homogeneously catalyzed hydrocarbon conversions. While hydrocarbons such as methane are abundant, methods to convert them to functionalized useful chemicals are scarce. We are investigating the feasibility of achieving a new method for activation of carbon-hydrogen (C-H) bonds, through hydrogen (H) atom transfer reactions from a carbon to a metal. If successful, this would provide a new mechanistic paradigm for C-H bond activation. The intent is to produce metal-centered radicals, initially focusing on the transition metal osmium, which is well-known to form very strong bonds to hydrogen. The metal radicals will be generated by photochemical homolysis of metal-metal bonded precursors. The carbon-to-metal H atom transfer is being examined using time-resolved transient infrared spectroscopy.

This program is supported by a Laboratory-Directed Research and Development Grant (LDRD). We acknowledge Brookhaven National Laboratory for this support.

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
