My research interests over the years centered on the development of nuclear magnetic resonance (NMR) techniques and their application to the study of the structures and properties of main group organometallic compounds, especially organolithium compounds. Organolithium compounds are used commercially in the preparation of pharmaceuticals, agricultural chemicals, and even polymers for truck tires. Without a knowledge of the structures and properties of the compounds, development and optimization of their use is by trial and error. By understanding their properties, their use can be developed in a rational fashion. In fact, we designed and developed several new organolithium compounds which have specific applications to organic synthesis. In the world of organolithium chemistry there are always exciting new discoveries to be made. It has been a real thrill to discover an entire new class of compounds (lithium hydride/lithium alkoxide mixed aggregates) and have the opportunity to explore their chemistry. Most people outside of science can understand the thrill of exploration of big science (underwater exploration or trips to Antarctica), but finding new compounds never before known by anyone else in the world is just as exciting, just as cutting-edge, and may ultimately have more impact on our day-to-day existence. The synthetic techniques used to make the compounds (including the vacuum line shown on the right) and the NMR techniques we used to study them have much broader use. Therefore synthesizing and studying these compounds also served as powerful training tools for students.
