Synthesis Of Bipyridine-Derived Iron Catalysts For Hydrogenation, Jack Elder
Synthesis Of Bipyridine-Derived Iron Catalysts For Hydrogenation, Jack Elder
Summer Research
Industrially, alkene and carbonyl hydrogenation reactions are catalyzed by iridium, rhodium and ruthenium-centered catalysts. These highly toxic metals are very expensive, both to attain and to dispose of after degradation. This ongoing research seeks to investigate cleaner and more economical alternative catalysts by synthesizing and testing a bipyridine-derived iron catalyst utilizing the unconventional ligand-assisted heterolytic cleavage of hydrogen mechanism to facilitate double bond hydrogenation. In the time allotted, this segment of research sought to synthesize the two catalyst ligands 6-hydroxy-2,2’-bipyrdine and 6,6’-dihydroxy-2,2’-bipyridine, and to model ligand-iron attachment using commercially available iron complexes. The former of the two ligands was synthesized …

Development Of New Arsenic Based Amidation Catalysts, Cameron Chrisman
Summer Research
The formation of amides is a reaction that is contucted on a multi-ton scale annually in the pharmaceutical industry. Because the reaction requires the use of toxic and expensive reagents and because a substantial ammount of waste is generated, much effort is being devoted to eliminating both of these limitations. Current research is aimed at finding an efficient catalyst for this reaction that will significantly reduce waste and can be recycled. While some catalysts have been developed for this reaction, currently there are no catalysts that are efficient enough to be used on a large scale. Studies in the Boisvert …
