  • The synthesis and electrocyclization of some linear and cross-conjugated hexatrienes

    Creator:
    Hilton, Charles Bruce
    Abstract:
    As part of the continuing investigation of the thermal cis- 1, 3, 5-hexatriene to 1,3-cyclohexadiene rearrangement, four new trienes and a cross-conjugated pentaene have been prepared and their thermal reactions studied. A new route to the synthesis of highly substituted trienes has been developed. The synthesis of three of these...

  • Steroid organoborane reactions

    Creator:
    Byall, Elliott Bruce
    Abstract:
    Steroid organoboranes have been found to be useful synthetic intermediates. Attempted pyrolyses, based on simple trialkylborane cyclizations, have not yielded C-19 or C-18 functionalized steroids, but have produced isomerized systems not otherwise available. Thus, hydroboration of cholesterol followed by pyrolysis at 215° gives 31% of 2-cholestene-6α-ol and 49% of a...

  • Application of flow injection analysis to enzymatic fluorescence kinetic methods

    Creator:
    Elliott, Colin Bruce
    Abstract:
    Studies of the use of NADH as the monitored fluorophore for enzymatic fluorescence kinetic methods are discussed. Interference studies for the detection of NADH and the adaptation and optimization of fluorescence kinetic measurements to four serum assays are also described. A microcomputer-controlled flow injection analysis (FIA) system was designed and...

  • A quadratic programming routine for the statistical analysis of gas chromatographic data

    Creator:
    Elliott, Stanley Claud, Jr
    Abstract:
    A quadratic programming method was developed for the statistical analysis of gas chromatographic data. The method was applied to three types of flavor extracts, peppermint, hops and brewed tea. The brewed tea data had to be abandoned because of the singularity of its coveriance matrix. In all cases tried the...

  • Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

    Creator:
    Dorn, Shelby E.
    Abstract:
    In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...

  • A Diels-Alder approach to biaryl synthesis

    Creator:
    Ashburn, Bradley O.
    Abstract:
    An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...

  • Sample entraining multi-electrode plasma sources for atomic emission spectroscopy

    Creator:
    Lee, Gae Ho
    Abstract:
    Plasma sources with multiple electrodes have been developed and characterized in this research for atomic emission spectroscopy. Multi-electrode plasma sources use electrodes to shape the plasma in order to continuously entrain a sample stream in the center of hot plasma, in a manner similar to an inductively coupled plasma (ICP)...

  • Analytical method development for the identification, detection, and quantification of emerging environmental contaminants in complex matrices

    Creator:
    Place, Benjamin J.
    Abstract:
    The development of analytical methods for emerging contaminants creates many unique challenges for analytical chemists. By their nature, emerging contaminants have inherent data gaps related to their environmental occurrence, fate, and impact. This dissertation is a compilation of three studies related to method development for the structural identification of emerging...

  • Structure-property relationships in oxides containing tellurium

    Creator:

    Abstract:
    Oxides of post-transition metals often show unique structures and properties due to the presence of lone pair electrons and the diffused s orbitals. The present work focuses on synthesis and characterizations of oxides containing Te, a heavy post transition metal. New series of pyrochlore oxides of the formula Cs(M,Te)₂O₆ (M...
