Imidazolidinones in amine catalysis
… spectrometry. In Chapter 4, a hybrid secondary amine is designed based upon the diarylprolinol ether and imidazolidinone scaffold. In Chapter 5, the 3-position of the imidazolidinone ring is investigated as a potential site to install electron withdrawing groups to influence the catalytic cycle. …

New axially chiral amine organocatalysts
… reported for the synthesis and use of tertiary amine organocatalysts based on the now ubiquitous binaphthyl backbone. The tertiary amines synthesized were shown to be effective nitrogen transfer reagents in the asymmetric aziridination of chalcone substrates, with enantiomeric excesses of up to …

Charge-Transfer Complexes for Amine Synthesis
… reaction was developed, combining secondary amines, cyclopropyl carboxaldehydes and alkenes, to generate cyclopentyl methylamines. To initiate the fragmentation step, single-electron reduction of alkyliminium ions to α-amino radicals was achieved, using an aromatic thiol and visible light …

Production of novel amine oxidases from microorganisms
… over-expression of an industrially important monoamine oxidase was attempted using different expression systems, both homologous and heterologous, and the optimum conditions for the industrial production were established. Amine oxidases exhibit stereoselectivity, and, therefore, can potentially be …

Liquid-Amine Infused Surfaces for Carbon Capture
… surfaces are designed to be readily wet by pure amine liquids to form wetting infused layers, retained by capillary forces, of order tens of microns in thickness. These stationary wetting layers capture CO<sub>2</sub> via a reaction to form carbamate. The large interfacial areas per unit volume …

Physiochemical properties of nonaqueous amine-containing electrolytes
… have demonstrated the viability of using amines to electrochemically activate CO2 before reduction and yield kinetic benefits, but little research has been done to optimize this new system. This thesis investigates the reduction of amine-activated CO2 and the properties of nonaqueous …

Activated carbon catalyzed nitrosamine formation via amine nitrosation
Nitrosamines have garnered increasing attention from researchers and policy makers in recent years due to potential human health implications associated with their unintentional formation in water and wastewater treatment facilities. This work addresses a crucial nitrosamine formation pathway …

Reductive metabolism of aliphatic tertiary amine n-oxides.
… the feasibility of using aliphatic tertiary amine N-oxides as antiarrhythmic agent prodrugs. Lignocaine was selected as a candidate for prodrug development, because the N-oxide is a non-active, polar derivative of lignocaine and the drug of choice for ventricular arrhythmia, a symptom …

Carbon Dioxide Capture With Amine Functionlized Graphene Oxide
Abstract: amine functionalized graphene oxide was used as sorbent in order to achieve carbon dioxide capture. In this study, micro size graphite flakes was prepared according to modified hummers method and "hummers' method with additional kmno4." Graphene oxide was then functionalized with …

Self-Assembly of Calix[4]Arene Amine Derivatives
A new family of calix[4]arene amine derivatives, which have been functionalised on both the upper and lower rim have been developed as potential duel metal ion binding complexes, and all were fully characterised. The lower rim was first functionalised with various groups such as benzyls and …
