Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

O Criador:: 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...

Part I: Synthetic Studies toward C10-functionalized Lycopodium Alkaloids. Part II: Exploration of the Pummerer Cyclization and Its Application to the Total Syntheses of the Abietane Diterpenoids

O Criador:: Li, Xin
Abstract:: This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...

Gas phase x-ray photoelectron spectroscopy of some ketone compounds

O Criador:: 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....

The development and characterization of miniature spectrometers for measuring the redox status of environmental samples

O Criador:: Cantrell, Kevin
Abstract:: A spectrometer, here denoted a Simple, Low-power, Inexpensive. Microcontroller-based or SLIM spectrometer. was developed that exploits the small size and low cost of solid-state electronic devices. This approach results in customizable spectrometers that are considerably less expensive and smaller than traditional instrumentation. The performance of the SLIM spectrometer was evaluated...

Synthesis and oxidation of metal-thiolate compounds which mimic the active site function of thiolate dioxygenase enzymes

O Criador:: Schussel, Leonard J.
Abstract:: Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand. The compound is a reasonably air-stable iron(III)-thiolate that contains a linear tri-iron cluster with each iron bridged to the adjacent iron by...

Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

O Criador:: Ferreira, Andrew
Abstract:: The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

Synthesis and oxidation of cysteine- and penicillamine- containing Fe(III) and Co(III) complexes. Analogs for the active metal sites of the cysteine and cysteamine dioxygenases

O Criador:: Miller, Krys J.
Abstract:: The first part of this thesis describes a study of the characteristics of oxidation of a 1:2 iron(III):thiolate system in methanolic solution and in water. This system was investigated as a potential analog for the cysteine- and cysteamine-dioxygenase catalyzed 0₂-oxidation of cysteine and cysteamine, respectively, to the corresponding sulfinic acids....

Part I: Synthetic studies toward the southern portion of Azaspiracid-1; Part II: Total synthesis of amphidinolide B₁ and the proposed structure of amphidinolide B₂

O Criador:: Lu, Liang
Abstract:: The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the synthesis of southern FGHI ring system...

Electrochemical studies of liquid chlorocuprates(I)

O Criador:: Silkey, James R.
Abstract:: This research emphasized fundamental physical and electrochemical studies of systems based on the room temperature fused salt, triethyl-ammonium dichlorocuprate(I). Such systems, which must be maintained under a protective atmosphere, were also used in some preliminary battery studies. Spectra of dark green solutions of copper (II) chloride in triethylammonium dichlorocuprate(I) obey...
