The Organic Division at UC Merced has a strong background in physical organic chemistry that empowers the development and understanding of synthetic reactions. Ryan Baxter and Ben Stokes are developing new catalytic reactions of inexpensive feedstock chemicals. Ryan uses kinetic analysis to guide the development of metal-catalyzed single-electron transformations, while Ben investigates catalytic asymmetric transformations backed by classical physical organic techniques.
