Endean, Riley Thomas

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...

Synthetic organic chemistry is an area that has seen incredible growth through the years. The level of molecular complexity that can be achieved through available synthetic methods today is remarkable. Still, as the field continues to progress, increasing focus is being placed upon the strategic...

Asymmetric synthesis is one of the most important areas of organic chemistry. Despite of the prevalence of asymmetric catalysts, there is still room for improved catalyst systems. Chapter 2 describes the design and evaluation of a new Lewis acid-assisted Lewis acid (LLA) catalyst system. Many...

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....

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-,...

Carboxylic acids are a ubiquitous class of molecules in the field of organic chemistry and represent versatile building blocks in synthetic chemistry. Methods that enable the formation of new carbon–carbon or carbon–heteroatom bonds from carboxylic acids via the extrusion of carbon dioxide can...

The study of heterobimetallic complexes (having two different metal atoms) involves combining the unique properties of each metal, which can give rise to interesting contrasts in reactivity compared to either metal alone. With two different metals incorporated into one complex, a more diverse...

Lummis, Paul A

The research presented in this thesis details the synthesis of transition metal hydride complexes, with the focus on utilising these complexes for (a) the dehydrocoupling of amine-borane adducts, and (b) the hydrosilylation and hydroboration of unsaturated organic moieties. In both instances,...

Bunquin, Jeffrey

Hydrocarbon-soluble, low-coordinate, phosphoranimide-supported complexes of the base metals (iron, cobalt and nickel) were developed and evaluated for a range of stoichiometric and catalytic bond-forming and bond-breaking transformations. An unprecedented family of tetrametallic clusters of Co(I)...

Salt metathesis between CoCl2 and [KNPEt3]n provides a new route to the halide-substituted cobalt phosphoranimide cluster [CoCl(NPEt3)]4. This cluster is a useful precursor for the preparation of alkyl-capped cobalt phosphoranimide complexes. The methylated heterocubane [CoMe(NPEt3)]4 was...
