  • Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

    Creator:
    Carlson, Erik
    Abstract:
    Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

  • Mechanisms of photohydrodebromination of bromoarenes

    Creator:
    Carlson, J. Eric
    Abstract:
    The photohydrodebromination of brominated paracyclophanes was studied to help elucidate the possible mechanistic pathways leading to product for bromoarenes in general. Several brominated [2.2]paracyclophanes were studied to determine the effect of substitution patterns on this reaction. [2.2]Paracyclophanes were chosen for this study in order to investigate possible intramolecular excimer formation...

  • High-resolution X-ray photoelectron spectroscopy of CO₂ and other small molecules

    Creator:
    Hahne, Jeffrey A.
    Abstract:
    The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...

  • Hydrogen abstraction from substituted t-butylbenzenes

    Creator:
    Harvey, Robert Louis
    Abstract:
    A study of the relative rates of the alkyl hydrogen abstraction from a series of meta and para substituted t-butylbenzenes by the chlorine atom at 70°C has been carried out. Application of the Hammett equation yielded a ρ value of -0.44 for the para compounds. Possible explanations for the non-linearity...

  • The photodecomposition of t-butyl bicyclo [7.1.0] decane-2-percarboxylate

    Creator:
    McRitchie, Donna Louise
    Abstract:
    This paper describes the synthesis of t-butyl bicyclo[7.1.0] decane-2-percarboxylate and its photolytic decomposition. The title compound was found to undergo simple homolytic cleavage when exposed to light of 2537 A; producing the cyclodecyl radical, carbon dioxide, and t-butoxy radical. The largest percentage of products arose from an intimate radical pair...

  • Photoelectron spectroscopy of small molecules

    Creator:
    Bomben, Kenneth D.
    Abstract:
    The photoelectron spectra of a series of halogenated molecules have been investigated in the gas phase. Both core-ionization energies and Auger kinetic energies were measured to probe the nature of the interaction that holds a core electron to the molecule. It was found that satellite structure (shake) could be used...

  • Gas phase x-ray photoelectron spectroscopy of compounds containing multiply-bonded oxygen

    Creator:
    Smith, Steven Reid
    Abstract:
    A new x-ray source capable of operating at up to 80 watts has been designed and developed, and put to use with the Oregon State University Cylindrical Electrostatic Analyzer. The new source produces over four times the photoelectron intensity of its predecessor, from gaseous samples, and accommodates a wider selection...

  • Gas phase x-ray photoelectron spectroscopy of some ketone compounds

    Creator:
    Situmeang, Rudy T. M.
    Abstract:
    The photoelectron spectra of a series of ketone compounds have been investigated in the gas phase. Core ionization energies were measured to probe the effects of molecular size and connectivity number on core ionization energies. It was found that core ionization energies roughly decrease with increasing connectivity number as expected....

    Creator:
    Chambers, Scott Alexander
    Abstract:
    The satellite structure ("shake-up") present in the X-ray photoelectron spectra of several planar molecules containing double bonds has been investigated in the gas phase. This set consists of three five-membered heterocyclic molecules, ethylene and two of its fluorinated analogs, and benzene with three of its fluorinated analogs. In addition, core...
