Exploring The Chemistry Of Asymmetric Phosphines & Phosphinidene Sulfides, Taylor E. Pritchard
Exploring The Chemistry Of Asymmetric Phosphines & Phosphinidene Sulfides, Taylor E. Pritchard
Electronic Thesis and Dissertation Repository
The field of low-coordinate main group chemistry has seen huge development in the last 30 years, with novel compounds that demonstrate unique structures and reactivity. Isolation of these species has relied on thoughtfully designed substituents normally containing substructure steric bulk. The area of phosphinidene chalcogenide isolation and transfer remains poorly understood by comparison. In this context, the major focus of thesis was on the development of a room-temperature method for the transfer of RP=S moieties with and without sterically demanding substituents. The preparation and complete characterization of new asymmetric phosphines with m-terphenyl ligands was also reported. In Chapter 2, …
Exploring The Synthesis, Structure, And Reactivity Of Phosphorus-Chalcogen Heterocycles, Cameron Graham
Exploring The Synthesis, Structure, And Reactivity Of Phosphorus-Chalcogen Heterocycles, Cameron Graham
Electronic Thesis and Dissertation Repository
In recent years, the field of low-coordinate main group chemistry has seen significant research interest due to their unique structures and unprecedented reactivity. Conversely, the area of phosphinidene chalcogenides, a low-coordinate phosphorus and chalcogen species, have yet to be thoroughly explored. In this context, this dissertation describes the synthesis of a number of phosphorus-chalcogen heterocycles that can be degraded to provide stoichiometric access to low-coordinate phosphorus species. The ability for successful P-Ch transfer relies on using a bulky m-terphenyl group at phosphorus that provides enough steric bulk to kinetically stabilize the phosphorus centre, but also accommodating enough to allow …
Coordination And Organometallic Chemistry Of Novel Gallium Complexes: Synthesis, Reactivity And Spectroscopy, Jeremy L. Bourque
Coordination And Organometallic Chemistry Of Novel Gallium Complexes: Synthesis, Reactivity And Spectroscopy, Jeremy L. Bourque
Electronic Thesis and Dissertation Repository
The work described in this thesis incorporates three main themes: the synthesis and reactivity of new coordination and organometallic gallium compounds, and the chemical state determination of molecular gallium complexes using XPS and XAS. The coordination chemistry of low valent gallium cations was explored using macrocyclic ethers as ligands. The experimental oxidation number, or chemical state, of newly synthesized low valent gallium cationic complexes was compared to known compounds to allow for the assessment of the electronic environment at gallium. The organometallic chemistry of gallium was examined using donor ligands to stabilize monomeric organogallium(III) compounds, demonstrating the ability to substitute …
