Imidazole-Containing Polymerized Ionic Liquids for Emerging Applications: From Gene Delivery to Thermoplastic Elastomers
Novel imidazole-containing polyelectrolytes based on poly(1-vinylimidazole) (poly(1VIM)) were functionalized with various hydroxyalkyl-substituents to investigate the influence of charge density and hydrogen bonding on nonviral DNA delivery. Copolymers with higher charge densities exhibited …

Synthesis of imidazole schiff base ligands, their silver (I) complexes and their activities against candida albicans
… this thesis concerns the synthesis of ca. 50 new imidazole-containing Schiff base ligands, the formation of their Ag(I) complexes and their evaluation as agents for inhibiting the growth of the fungal pathogen, Candida albicans. The synthesis of some Schiff base ligands proved problematic and the …

C-H on the Oxo Ferryl Wheel: Comparison of Pyridine and Imidazole-Substituted Ligands for C-H Activation and Functionalization
… We next turned to addressing the lack of imidazole-substituted models through ligands BItCHEN and <sup>nBu</sup>BIMEN. Translating the previously established BItCHEN structure to our simple and modular synthetic approach ultimately proved unsuccessful. Therefore, we focused on …

The Synthesis and Reactions of 2-Diazo-4,5-Bis(trifluoromethyl)imidazole, a Carbene Precursor to Stable Ylide and Hypervalent Compounds
The synthesis of 2-diazo-4,5-bis(trifluoromethyl)imidazole is discussed. An azo-linkage is used as a masked amine source in a fluorination reaction in which carboxylic acids are converted to trifluoromethyl groups. The azo compound is then hydrogenolyzed to the diazo compound precursor, …

Diastereoselective Lithiation-Substitution of N-Silyl-Protected-(S)-Tetrahydro-1H-pyrrolo[1,2-c]imidazole-3(2H)-ones and Applications of Their Derivatives
This thesis describes a method involving the preparation of an L-proline-derived imidazolone protected with an N-triethylsilyl group that undergoes diastereoselective lithiation followed by electrophile quench to give C5-substituted products with syn stereochemistry. The N-silylated derivatives may …

Investigating the Tyrosine-Histidine Linkage in the Copper B Site of Cytochrome C Oxidase: Model Studies Utilizing a Zinc Imidazole-Phenol Containing Complex
… synthesized incorporating an ortho substituted imidazole-phenol moiety. The resultant Zn(II) complex, [Zn(BPAIP)(Br)]+, was found to exhibit a decreased pK A (8.24) and increased oxidation potential relative to the unbound BPAIP. In addition, the stability of [Zn(BPAIP)(Br)]+ in buffered D2O was …
