The Investigation of Nickel-Based Catalysts for the Oxidative Dehydrogenation of Ethane Justin Lane ParkDepartment of Chemistry & Biochemistry, BYU Doctor of Philosophy Chemistry The advancement of creating ethylene from ethane via oxidative dehydrogenation (ODH) rather than the traditional direct dehydrogenation is right on the cusp of commercialization. The oxidative pathway provides a novel route that reduces the operating temperature of this reaction by 400-500°C. A variety of metals including Mo, V, and Ni that have redox properties suitable for the partial oxidation of small chain alkanes have been investigated. Currently, a MoVNbTe oxide is the most promising catalyst but it …

Development Of Nickel Catalyzed Cross-Coupling Methodologies, Ryan J. Key
Theses and Dissertations
In this work, we have addressed some of the issues surrounding catalytic crosscoupling reactions by using a nickel terpyridine catalyst, [Ni(tpy)(py)(CH3CN)2](PF6)2 in the Buchwald-Hartwig amination reaction and a functionalized variant, [(2,2':6',2''- terpyridine-4'-benzoic acid)Ni(II)]Cl2 on SiO2, in Suzuki coupling. These processes are unique in the approaches taken to achieve reactivity. In the Buchwald-Hartwig amination reaction, we used photoredox dual catalytic methods to achieve a sustainable approach to generate secondary and tertiary amines. This report is unique in many ways; most importantly, this method uses N-centered radicals to generate new C-N bonds. This report is also the first report to show generation …
