Study of heteroaromatic enediyne and substituted benzothiophene synthesis with relative reactivity of substituted aryl iodides in the Sonogashira reaction
(2006)
Enediyne compounds have captured the imagination of chemists since their
discovery as a class of natural products. Because of their cytotoxicity, these compounds
are not suitable for use in cancer treatment. As a result, ...
Synthesis and study of palladium-containing nanomaterials for hydrogen technologies
(2010)
We are currently facing a climate change and global warming effect due to the emission of greenhouse gases from our existing energy sources. A hydrogen-based economy is one solution to uphold our standard of living while ...
Ruthenium-Tris(Pyrazolyl)methane complexes as potential candidates for cancer chemotherapy agents
(2009)
The MeCN ligands of complex 1 were substitutionally inert, however, under forcing conditions the DMSO ligands of complex 2 were displaced by chelating 1,2-bis(diphenylphosphino)ethane to produce complex 6. Structural ...
Theoretical and experimental investigation of solvatochromic and photochromic materials
(2010)
This thesis includes a study of solvatochromic molecules in the liquid and gas phases, and a study of photochromic molecules in the solid phase. The solvatochromic molecules studied are Nile Red, Betaine 30 and its penta ...
Ruthenium half-sandwich complexes containing novel anionic (phosphino) tetraphenylborate ligands
(2009)
In an attempt to expand upon previous work involving ruthenium-arene complexes bearing anionic (phosphino) tetraphenylborate ligands, and possibly provide further insight into the products obtained, a series of metal ...
Synthesis of novel Lipid A analogs as potential ligands for toll-like receptor 4
(2009)
Lipid A, the glycolipid component of Gram-negative bacterial lipopolysaccharide has been shown to engage the Toll-like receptor 4 (TLR4) signalling pathway. While this signalling cascade results in cellular mediators which ...
Structural determinations by analytical analysis of 7-phosphanorbornadiene derivatives and amino acid enantiomers
(2000)
The purpose of Chapter 1 is to create a bicyclic, two-coordinate phosphorus derivative in the
form of a 2,3-benzo-l,4,5,6-tetraphenyl-7-phosphanorbomadiene anion and measure its
experimental 3,P NMR chemical shift. This ...
Synthesis and electrochemical study of PtIr nanomaterials
(2008)
Nanomaterials have a number of unique chemical and physical properties and have
attracted tremendous attention due to their potential for applications in a variety of areas
including fuel cell and biosensor development. ...
Synthesis and cytotoxic activity of diosgenyl saponin analogues
(2008)
Saponins are naturally occurring glycosides that are widely distributed in the plant kingdom and lower marine organisms. Saponins consist of a carbohydrate chain attached to either a steroid or triterpene aglycone. Diosgenyl ...
