Asymmetric Nitrene Transfer Reactions With Azides Via Co(Ii)-Based Metalloradical Catalysis (Mrc), Jingran Tao
Asymmetric Nitrene Transfer Reactions With Azides Via Co(Ii)-Based Metalloradical Catalysis (Mrc), Jingran Tao
USF Tampa Graduate Theses and Dissertations
Asymmetric nitrene transfer reactions via metalloradical catalysis (MRC) with
azides has attracted research interest because of its fundamental and practical importance.
The resulting nitrogen-containing units are recurrent motifs in biologically important
molecules and can serve as versatile precursors in organic synthesis.
The [Co(D2-Por*)] have emerged as a new class of catalysts for asymmetric
aziridination and C-H amination. These metalloradical catalysts have been shown to be
highly effective for the asymmetric intermolecular aziridination of a broad scope of
substrates with different classes of azides with excellent to good enantioselectivity. The
intramolecular C-H amination utilizing various azides can allow for the construction …

Model Pt- And Pd-Based Electrocatalysts For Low Temperature Fuel Cells Applications, Selasi Ofoe Blavo
USF Tampa Graduate Theses and Dissertations
In the search for alternative energy technologies, low temperature fuel cells continue to feature as technologies with the most promise for mass commercialization. Among the low temperature fuel cells, alkaline and proton exchange membrane fuel cells are the most popular. Alkaline fuel cells have typically been used for water generation as well as auxiliary power for space shuttles. Their bulkiness however makes them undesirable for other applications, especially in automobiles, where there is a great demand for alternative technologies to internal combustion engines. Proton exchange membrane fuel cells on the other hand possess numerous qualities including their compact size, high …
