With this award from the Inorganic, Bioinorganic and Organo-                    metallic Chemistry Program, Louis Messerle of the University of                 Iowa will investigate organometallic compounds of the early                     transition metals such as zirconium, hafnium, vanadium and                      tantalum as possible agents for the activation of carbon-                       hydrogen bonds of alkanes and alkenes. The discovery of a good                  carbon-hydrogen activation catalyst would allow the use of                      methane and lower hydrocarbons from natural gas or biomass                      decomposition as an alternative to petroleum as an energy                       source and feedstock for much of the synthetic organic chemical                 industry.                                                                                                                                                       The emphasis in this work will be the synthesis and study of                    the alkane/alkene reactivity of metal- dinuclear compounds,                     such as doubly bonded dizirconium and triply bonded ditantalum                  complexes in intermediate oxidation states. Ancillary ligands                   such as mono- and bi-dentate tertiary phosphines and penta-                     methylcyclopentadienyl will be used to minimize competitive                     intramolecular C-H activation. Functionalization studies, such                  as carbonylation, bromination, monooxidation and photochemical                  dehydrogenation, on the new alkyl/vinyl(hydrido)dinuclear                       products will be investigated.
