Expert in Homogeneous Catalysis, Water oxidation, CH oxidation, inorganic chemistry, organometallic chemistry
Expert is knowledgeable of all aspects of the synthesis, structure, uses, and reactions of organometallic compounds of the transition metals and the main group, including processes applicable to organic chemistry. Expert wrote the book entitled Organometallic Chemistry of The Transition Metals. He can answer questions on the synthesis, structure, reactions, and physical properties of organometallic compounds, both of the transition metals and the main group. He has employed NMR, infrared and UV-visual mass spectroscopy, and crystallography in his studies.
Expert has applied his knowledge of chemistry to develop methods for the abatement and disposal of ozone depleting gases, especially chlorofluorocarbons (CFCs), fluorocarbon gases, and polymers. Working with associate Juan Burdeniuc, Expert discovered a new method for disposing of CFCs. The procedure involves a simple chemical process using sodium oxalate to turn CFCs into harmless byproducts. Sodium oxalate is inexpensive and readily available and when reacted with CFCs produces carbon, sodium chloride, sodium fluoride, and carbon dioxide as byproducts. Expert found that by lowering the temperature of the reaction different byproducts will result, including valuable fluoro-compounds (perfluoroarenes, which are valuable chemical intermediates). He maintains that the discovery is also useful because various regimes can be employed to produce a variety of possible products.
Expert has conducted hydrogen bonding studies to design improved catalysts and receptors for simple substrates. Recently, while working with his team of researchers, Expert was studying iridium hydride complexes when he noticed that positively and negatively charged hydrogen atoms were found close together a complex way, that indicated an attraction between them. The discovery led to the recognition of the "dihydrogen bond," an attractive interaction between two hydrogens.
Expert is now investigating whether dihydrogen bonds can be put to practical use. The modification of transition metal catalysts, used for accelerating and controlling everything from polymerization to drug synthesis, might be one application. Expert's team is also introducing H-bonding groups into synthetic catalysts (including Wilkinson's hydrogenation catalyst) with the idea of seeing rate increases or selectivity changes, with asymmetric catalysis as a possibility. He has worked with asymmetric hydrogenation, hydrosilation, hydroformylation, oxidation, and hydroboration.
Expert has extensive experience designing reactions using clues from enzyme chemistry, especially hydrogenase, methane mono-oxygenase, photosystem II, and nitrogenase.
In research funded by the Office of Basic Energy Sciences, Chemical Sciences Division, Expert has achieved two noteworthy discoveries that constitute a breakthrough in the selective activation of C-F bonds. Using a method that employs the energy from photochemically-excited mercury atoms to convert relatively unreactive alkanes and other organic molecules to novel organic products, Expert has recently examined the activation of C-F bonds in perfluoroalkanes. After activating C-F bonds using photochemically-excited mercury atoms, Expert and his staff discovered a successful non-mercury system for the defluorination of perfluoroalkanes. Success in this area could provide new avenues to a wide range of value-added industrial and biomedical products.
Expert has used organoaluminum compounds extensively in synthesis reactions. He has experience handling the compounds and characterizing the acid-based adducts of these compounds. He is familiar with inorganic applications of organoaluminum chemistry, catalytic applications, and the partial hydrolysis to MAO.
Expert has designed or improved many reactions involving light gases. He has worked with H2, CO, CO2, CH4, CF4, C2F6, and NH3.
A significant portion of Expert's group is now devoted to organofluorine chemistry. He has worked with the defluorination reactions of organofluorine compounds, nucleophilic attack and electron transfer, and the characterization by spectroscopic and structural methods. He has conducted the examination of physical properties and the surface modification of PTFE polymers.
Expert has developed a number of high-throughput screens for soluble and polymer-supported homogeneous catalysts to assay for activity and selectivity. Libraries of ligands and the derived metal catalysts have been prepared on polystyrene beads and assayed by using reactive dyes, reactive fluorescent agents, and NMR analysis of high-activity catalysts for selectivity. He has also synthesized and characterized new dyes.
Expert has applied NMR techniques to numerous inorganic and organometallic studies.
Expert has analyzed partial alkane and hydrocarbon oxidation with O2 or O atom donors as oxidants. He is familiar with radical versus nonradical pathways. He can advise clients on mechanistic issues, the design of catalysts, and the use of unconventional media.
