Ionic organocatalysis

McGrath, Trevor Adam (Halifax, N.S. : Saint Mary's University, 2014)

A method for synthesizing ionic thiourea based organocatalysts was elucidated. Two ionic organocatalysts were then successfully synthesized and fully characterized. A thiourea containing a pyrrolidinium moiety was shown ...
Langmuir-Blodgett deposition of functionalized AuNRs towards multidimensional LSPR sensing

MacMillan, Presley Sarah (Halifax, N.S. : Saint Mary's University, 2017)

Understanding the surface plasmon resonance properties of gold nanorods (AuNRs) and exploring their sensitivity has attracted much attention due to the potential applications in the biomedical field; including detection ...
A mechanochemical approach for organocatalysis and improved synthesis of gemini surfactants

Campbell, Jacob William (Halifax, N.S. : Saint Mary's University, 2020)

Mechanochemistry and organocatalysis provide green synthetic methods for chemical reactions. Reported herein are Morita-Baylis-Hilman reactions co-catalyzed by 1,4-diazabicyclo[2.2.2]octane, DABCO, and 1-(4-(3-(3,5-bis(t ...
N-demethylation of alkaloids using nanoscale zero valent iron

Awalt, Jon Kyle (Halifax, N.S. : Saint Mary's University, 2016)

The N-demethylation of naturally occurring opiate compounds is a necessary step in the synthesis of many pseudo-opioid pharmaceuticals. Such drugs have gained recent media attention in the fight against opiate addiction; ...
New electron-rich diketiminate ligands : an experimental and computational investigation on the isolation of reactive species

Land, Michael Alexander (Halifax, N.S. : Saint Mary's University, 2016)

Boron analogues of NHCs have long eluded detection, likely due to their predicted low singlet-to-triplet energy gap. Two new N,N’-chelating ligands have been prepared and investigations into their reactivity and coordinative ...
Nova Scotian bees as sources of antimicrobial compounds against American foulbrood disease

Kooshna, Prashansa (Halifax, N.S. : Saint Mary's University, 2020)

Honey bees, Apis mellifera, face many parasites and pathogens such as Paenibacillus larvae, the causal agent of American Foulbrood disease (AFB), a highly contagious disease. Honey bees rely on a diverse set of individual ...
Pairwise testing of Lentzea strains against Mycobacterium smegmatis to search for and identify new anti-tuberculosis compounds

Dayrit, Julie Anne (Halifax, N.S. : Saint Mary's University, 2020)

Tuberculosis remains one of the top ten causes of death worldwide. Therefore, immediate discovery of new antibiotic compounds is crucial for counteracting the evolving antibiotic resistance in strains of Mycobacterium ...
Phosphonium ion based salen derivatives for use in catalysis

Lavoie, Chris Mark (Halifax, N.S. : Saint Mary's University, 2014)

Schiff base ligands and their respective complexes are well established for use in asymmetric catalysis. With difficulty of separation of the catalyst from reaction mixtures being one of the more salient drawbacks to these ...
Phosphonium ionic liquid based salen ligands for use in catalysis

Prudhoe, Christine (Halifax, N.S. : Saint Mary's University, 2013)

Salen ligands and their corresponding complexes are well known in the field of asymmetric catalysis due to their success in stereoselective reactions. A method that easily allows for recycling of the catalyst without ...
Purification and total acid number reduction of raw diesel via column chromatography

Publicover, Ernlie A. (Halifax, N.S. : Saint Mary's University, 2018)

Crude petroleum products have impurities that are harmful to industrial equipment, vehicles, and the environment. The American Society of Testing and Materials (ASTM) is a regulatory body that controls the standards for ...
The reactions of carbon disulfide and sulfur dioxide with small carboxylate anions

Paula, Zoe Anne (Halifax, N.S. : Saint Mary's University, 2016)

In one form or another both acid gases and carboxylates have existed from prebiotic earth all the way to the present day. Here we have studied the reactions of carbon disulfide (CS[subscript 2]) and sulfur dioxide (SO[subscript ...
The [sigma]-hole interaction of 1,3-bis(2,6-diisopropylphenyl)imidazolidine [SiPr] with iodine-containing small molecules

Greene, Bradley H. C. (Halifax, N.S. : Saint Mary's University, 2016)

Iodine-containing small molecules, such as R-CC-I and I-CC-I, can form halogen bonds, interactions that arise from the electrostatic forces between a halogen and Lewis base. This interaction arises from the presence of a ...
Synthesis of novel first-row transition metal-N-heterocyclic carbene complexes and synthesis of N-heterocyclic carbene-functionalized linkers for metal organic frameworks

Hoare, Jacob Geoffrey (Halifax, N.S. : Saint Mary's University, 2022-04-26)

Although N-heterocyclic carbene ligands are highly versatile and powerful ligands in transition metal catalysis, complexes of N-heterocyclic carbenes with 3d metals are uncommon and frequently unstable. ...
The synthesis, characterization and modification of gold nanoparticles for use in SERS-based COVID-19 antibody testing

MacInnis, Marissa J. (Halifax, N.S. : Saint Mary's University, 2021)

The current COVID-19 pandemic has highlighted a need for rapid, point-of-care (POC) antibody testing. Antibody testing would allow for a determination of which members of the population have already been infected with the ...
