A New Approach to Molecular Hydrodesulfurization Catalysts: Allyl-capped Trialkylphosphoranimide-bridged Late First-row Transition Metal Clusters
DownloadFall 2017
A series of new trialkylphosphoranimide allyl-capped clusters [M(ƞ3-allyl)(NPR)3]2, (M = Fe, Co or Ni, R = Et, tBu or Ph) were synthesized. The nickel dimers [Ni(ƞ3-allyl)(NPR3)]2, R = Et, Ph are diamagnetic and have been fully characterized using NMR spectroscopy, X-ray crystallography,...

A thorough overview of esters and their reductions is presented. A large focus was placed on reductions via homogeneous catalytic hydrogenation. Although several ester hydrogenation systems have been developed, the production of highly enantioenriched alcohols has generally relied upon the usage...

Fall 2014
Activity, selectivity and stability enhancements often observed in bimetallic catalysts make them an inseparable part of today’s chemical industry. However, it is usually problematic to understand the real interactions resulting in such improvements due to the lack of control over the bimetallic...

Characterization of asphaltene molecular structures by cracking under hydrogenation conditions and prediction of the viscosity reduction from visbreaking of heavy oils
DownloadSpring 2013
The chemical building blocks that comprise petroleum asphaltenes were determined by cracking samples under conditions that minimized alterations to aromatic and cycloalkyl groups. Hydrogenation conditions that used tetralin as hydrogen-donor solvent, with an iron-based catalyst, allowed...

Design, Development and Mechanistic Study of Ruthenium-Based Catalysts for the Hydrogenation of Imides and Amides
DownloadSpring 2014
Prior mechanistic studies demonstrate that trans-[RuH2((R)-BINAP)((R,R)-dpen)] is a remarkably active carbonyl reducing agent at low-temperatures in THF-d8. This dissertation describes the monohydrogenation of cyclic meso-imides using this catalyst and related complexes under mild conditions....

Development of Ir- and Rh-Catalyzed Deoxygenation and Carbene Cross Coupling Reactions of Allylic Carbonates
DownloadFall 2016
Transition metal-catalyzed allylic substitution reactions are widely used for the selective formation of new bonds. This class of reaction has been extensively studied with a variety of nucleophiles and under optimized conditions that will furnish product in high yield and with high chemo-,...

The Noyori-type catalyst trans-Ru((R)-BINAP)(H)2((R,R)-dpen) (6) and its analogues are among the most active and enantioselective ketone hydrogenation systems reported to date. Its applications towards other types of carbonyl compounds are, however, understudied. This dissertation describes the...

Moghaddam, Reza B., Wang, Chao, Sorge, Jason B., Brett, Michael J., Bergens, Steven H.
Ir–Ni oxide nanoparticles were simply prepared by stirring IrCl3 and NiCl2 precursors in aqueous base under air. The activities of a series of IrNiyOx nanoparticles with different Ir-to-Ni ratios were measured toward water oxidation in 0.1 M H2SO4. The Ir-to-Ni ratio was 1:0.125 in the most...
