Synthesis/Inorganic/Organic

Research in the Widenhoefer group is directed toward the development and mechanistic analysis of new organotransition metal-catalyzed transformations for application in the synthesis of functionalized organic molecules. In particular, our group has a long-standing interest in the functionalization of C?CC multiple bonds with carbon and heteroatom nucleophiles catalyzed by electrophilic late transition metal complexes, with a recent focus on the synthetic and mechanistic aspect of gold(I) pi-activation catalysis. Current areas of inquiry include the following: 1) Gold(I) and Pt(II)-catalyzed hydroamination of alkenes an allenes. 2) Gold(I)-catalyzed dehydrative amination of underivatized allylic alcohols. 3) Synthesis and study of cationic, two-coordinate gold pi-complexes. 4) Evaluating the role of bis(gold) complexes in gold pi-activation catalysis. More detailed descriptions of these research projects can be found at our group web page.
