Preparation Of Polymeric Materials From Bio-Renewable Sources, Jason Douglas Smith
Preparation Of Polymeric Materials From Bio-Renewable Sources, Jason Douglas Smith
Theses and Dissertations
The focus of this project was to develop methodologies for the preparation of novel polymeric materials from bio-renewable sources. In order to complete this task we needed (a) unfettered access to bio-based materials and ways to convert them to value needed chemicals, as well as, (b) reaction protocols that would allow greater diversity during the synthesis of polymeric compounds so as to affect the properties of these materials.
Our research group has a background in converting plant-based materials like cellulose into value added chemicals employing catalytic reactions. The polymerization of these monomers was then conducted utilizing the Baylis-Hillman reaction. The …
Substituted Hydroxylamines As Nitrogen Transfer Reagents: Direct Synthetic Pathways To Structurally Rich Heteroatomic Scaffolds, Dylan John Quinn
Substituted Hydroxylamines As Nitrogen Transfer Reagents: Direct Synthetic Pathways To Structurally Rich Heteroatomic Scaffolds, Dylan John Quinn
Theses and Dissertations
Nitrogen is found in virtually all valuable chemical compounds. The abundance of atmospheric nitrogen however, is rendered inaccessible because of the strong N-N triple bond, ultimately preventing its practical utilization in synthetic organic synthesis. The development of powerful nitrogen transfer reagents, such as substituted hydroxylamine derivatives, have played an important role in the introduction of nitrogen into valuable chemical scaffolding.
Herein is reported the methodological development of synthetic nitrogen placement into a range of valuable heteroatomic compounds. This work shows that O-Substituted Hydroxylamine can be used to furnish small heteroatomic compounds, particularly nitriles. Whereas, N-Substituted Hydroxylamine can be employed to …
