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.
