Title:   Breaking Strong Bonds and Recovering Rare Earths: Adventures in Sustainable Chemistry

 

 Abstract:  Catalysis is one of the most powerful tools of green chemistry, enabling reactions with lower energy consumption and providing new pathways for bond formations. In particular, catalytically functionalizing C-H bonds (common in crude oil derived molecules) and C-O bonds (common in biomass) under mild conditions are critical reactions to enable more sustainable chemical methodologies. This presentation will showcase our recent research efforts in establishing non-directed, transition metal catalyzed C-H functionalizations and catalytic C-O bond activations through halide catalysis. Our approach aims at establishing a mechanistic understanding in order to translate this knowledge into broadly useful protocols for organic synthesis and biomass activation.

At the end of the materials lifecycle, inventing new technologies to provide sustainable sources of raw materials through recycling is another critical challenge for the movement towards a circular economy. Our efforts in this area take an approach similar to our developments in the area of catalysis: Based on understanding principles and mechanisms of materials flows, we use the principles of green chemistry to enable the design of novel, sustainable rare earth recovery technologies.
