Project Descriptions:

1. Oxygen and Nitrogen Complexes with Gold, Platinum, Palladium, Rhodium, and Iridium. Noble metals (platinum, palladium, rhodium, iridium, silver, and gold) are excellent catalysts for a number of important reactions involving oxygen and nitrogen containing molecules (Scheme 1). These reactions occur by bonding of the nitrogen and oxygen atoms to the metal atoms on the surfaces.

Since the surfaces are difficult to study my group is preparing and studying complexes containing oxygen and nitrogen atoms bonded to rhodium, iridium, palladium, platinum, and gold. An example of a recently prepared platinum complex is shown to the left. Our soluble molecular complexes, in contrast to the metal surfaces, are easily studied by solution (NMR, IR, etc) and solid state (X-ray diffraction) techniques. Their chemical properties give valuable information about how the catalytic reactions occur and may lead to new stoichiometric and catalytic processes.

2. Organometallic Chemistry on the Edge (of Polycyclic Aromatic Carbon Compounds)

2. Organometallic Chemistry on the Edge (of Polycyclic Aromatic Carbon Compounds)

In another project, we are preparing and studying complexes with a metal or metals bonded to the edge of polycyclic aromatic compounds. An example of a zirconium complex is shown in the figure on the left. Polycyclic aromatic carbon compounds and their derivatives are useful in a wide variety of applications in electronics, optics, and other materials areas. Our complexes can be reacted with a number of compounds to yield new derivatives and to "grow" the carbon framework. The development of this reaction chemistry has the exciting possibility of yielding a step-growth synthesis of carbon nanotubes and other fullerene structures (Scheme 2).
