  • 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...

  • Patterns of lipid changes with growth of chick sciatic nerve

    Creator:
    Munn, Hector John
    Abstract:
    Phospholipids and cerebrosides of the normal chick sciatic nerve were extracted by Folch procedures and separated with silica gel thin-layer chromatography using various chloroform-methanol solvents. The subsequent chemical assays were expressed as a function of the developmental stages of the chick from 15 days of incubation to 7 days after...

  • Broadening the scope of the modified-Julia reaction : a mild and stereoselective method for the synthesis of (Z)-configurated α,β-unsaturated lactones

    Creator:
    Giesbrecht, Heath Eugene
    Abstract:
    An intramolecular variant of the modified-Julia olefination was demonstrated by the synthesis of α,β-unsaturated lactones in a mild and (Z)-selective fashion. The lynchpin reagent (benzothiazol-2-sulfonyl) acetic acid was synthesized in a straightforward fashion in 86% overall yield from commercially available 2-mercaptobenzothiazole via conversion to ethyl (benzothiazol-2-ylthio)acetate by base mediated alkylation...

  • The normal vibrational analysis of polyacetaldehyde

    Creator:
    Lee, Dorothy
    Abstract:
    A method of calculating the normal vibrations of polymer molecules is presented in detail. The method is based on that used by Schachtschneider and Snyder in their analysis of polypropylene but has not heretofore been published. The factoring of the infinite matrix and reduction to the coordinates of the unit...

  • Expanding the scope of a Diels-Alder approach to biaryl synthesis

    Creator:
    Schwartz, Johanna Perkins
    Abstract:
    A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted biaryls can be produced in just three to four steps from commercially available materials utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will illustrate the ability of mono...

  • Solvent selectivity of several organoclay complexes

    Creator:
    Nee, Mary
    Abstract:
    Six organoclay complexes have been studied in terms of their selective adsorption from binary solutions of methanol and toluene. Analyses are based on differential refractometry methods. The isotherms were of the usual "S" type. The crossover points reveal trends in the organophilic nature of the interlaminar surfaces in these clay...

  • Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

    Creator:
    St. Clair, Akos Dominic
    Abstract:
    Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...

  • Organic Crystalline Solids : Investigating their Capability, Storage Mechanism and Structural Evolution in Dual-Ion Batteries

    Creator:
    Rodríguez Pérez, Ismael A.
    Abstract:
    Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

  • Measuring in situ reductive dechlorination rates in trichloroethene-contaminated groundwater

    Creator:
    Hageman, Kimberly J.
    Abstract:
    Trichloroethene (TCE) is the most frequently detected organic contaminant in groundwater, is classified as a probable human carcinogen, and exhibits toxicological effects on the human endocrine, immune, developmental, and reproductive systems. While significant research efforts have been devoted to the development of strategies for remediating TCE-contaminated groundwater, their advancement is...
