The Synthesis Of Biomimetic Tungsten And Molybdenum Complexes, John Sterling Cole Iii
The Synthesis Of Biomimetic Tungsten And Molybdenum Complexes, John Sterling Cole Iii
Honors Theses
The synthesis of novel biomimetic molybdenum and tungsten compounds that are potential model complexes for molybdenum and tungsten oxidase enzymes is being pursued. Model complexes such as these provide a better understanding of the basic chemistry of a metal center in an environment similar to that found in particular enzyme active sites. This understanding provides a good starting point for biologists or biochemists studying those biological systems. The first target complex will incorporate a tetradentate-S4 ligand (L) that features two biphenyl-S2 fragments joined by a propyl linker. The second target complex will incorporate a bidentate ligand (L') with a singly …

The Synthesis And Characterization Of Bicyclooxacalixarenes, Kevin J. Selby
Honors Theses
Bicyclooxacalixarenes were synthesized in high yield via a selective, room temperature Sn Ar reaction of phluoroglucinol with 2,6-dichloropyridines. Functionality on the 2,6-dichloropyridioe was varied by changing the electron-withdrawing groups in the 3 and 5 positions (using chlorine, nitro groups, and cyano groups) and the side-chains in the 4-position (using ethyl, butyl, phenyl and ρ-tolyl groups). The resulting cage-like molecules were studied by X-ray crystallography and tested for metal complexation.
