Breaking New Ground with the Suzuki-Miyaura Reaction: Stereoselective Cross-Couplings of 1,1-Diboronyl AlkanesDownload
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...
In every thermal upgrading process, short-chain hydrocarbons contain a part of the gas byproducts. These compounds are hydrogen-rich materials, which are considered as low value wastes. In this study, the efforts were made to catalytically convert these off-gases to liquid fuels. Synthetic gases...
Design and evaluation of a new Lewis acid-assisted Lewis acid catalyst system and further applications of a double-allylation reagentDownload
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...
Design, Development and Mechanistic Study of Ruthenium-Based Catalysts for the Hydrogenation of Imides and AmidesDownload
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 CarbonatesDownload
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-,...
Dicarbenes as bridges in mixed-metal systems
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...
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,...
Empowering the Base Metals: Rational Design of Homogeneous Catalysts for Hydrotreatment, and Reduction of Organic Unsaturates
Empowering the Base Metals: Rational Design of Homogeneous Catalysts for Hydrotreatment, and Reduction of Organic UnsaturatesDownload
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)...
Cyclic steam stimulation (CSS) and steam assisted gravity drainage (SAGD) are the most commonly applied techniques used for heavy oil (HO) and bitumen (B) recovery. However, these methods, especially CSS, suffer from low recovery factor and production of highly viscous oil that requires...
