Molecular Oxygen as a Reagent in Late Transition Metal Organometallic Chemistry
From environmental and economic standpoints, molecular oxygen represents the ideal oxidant for chemical transformations. It is readily available, inexpensive (particularly if used without separation from air) and environmentally benign. However, more expensive and/or hazardous oxidants are often employed in homogeneous metal-catalyzed oxidation reactions. An insufficient knowledge of how transition metal complexes react with molecular oxygen has inhibited catalyst design of effective aerobic systems. Kinetic and mechanistic studies of the reactions of oxygen with various late metal complexes, including metal alkyls and hydrides, will be presented along with our nascent mechanistic understanding of these reactions. The generality of these aerobic oxidation reactions and the potential for incorporation into hydrocarbon functionalization strategies will be discussed.
Research in Professor Goldberg’s group is focused on the development of new catalytic systems to efficiently produce chemicals and fuels from a range of available feedstocks. We are interested in transforming both highly saturated feedstocks, such as natural gas and alkanes, as well as highly oxygenated materials like CO2 and those found in biomass. Using catalysis, we seek to develop new environmentally responsible and economically viable methods to convert these feedstocks to more valuable organic products.
Professor Goldberg received her artium baccalaureus (A.B.) degree from Barnard College of Columbia University in New York City. As an undergraduate, she pursued research projects with at Cornell University, Columbia University, and AT&T Laboratories. She then went on to the University of California, Berkeley, where she earned her doctorate in chemistry. Following a post-doctoral year at Ohio State University, she joined the faculty at Illinois State University, a primarily undergraduate institution. She moved to the University of Washington where she became the first Raymon E. and Rosellen M. Lawton Distinguished Scholar in Chemistry and the first Nicole A. Boand Endowed Professor of Chemistry. She also served as director of the first National Science Foundation-funded Phase II Center for Chemical Innovation, the Center for Enabling New Technologies through Catalysis. In 2017, she moved to the University of Pennsylvania as a Vagelos Professor of Energy Research and is the inaugural director of the Vagelos Institute of Energy Science and Technology.
