  • Investigations into the mechanism of the photodechlorination of pentachlorobenzene

    Creator:
    Schmidt, Robert Dean
    Abstract:
    Several experiments were undertaken to investigate the mechanism of photodechlorination of pentachlorobenzene. The thermal methoxydechlorination reaction of pentachlorobenzene was studied. In DMSO at 50 °C sodium methoxide reacts smoothly with pentachlorobenzene to give three tetrachloroanisole isomers. A second-order kinetic plot for this reaction is linear to high precision, indicating that...

  • The use of the Diels-Alder reaction in asymmetric synthesis

    Creator:
    Dei Rossi, Dale Raymond
    Abstract:
    The Diels-Alder reaction represents a promising tool for use in asymmetric synthesis. The reaction involves a rigid transition state that facilitates the formation of one diastereomeric transition state and is reversible. This satisfies two necessary criteria for asymmetric synthesis. The Diels-Alder reactions of 1,l-dialkylspiro[2.4]-4,6- heptadienes with maleic anhydride and p-benzoquinone...

  • The photochemistry of polychlorobenzenes in micellar media

    Creator:
    Lee, Youn-Sik
    Abstract:
    Photolysis of pentachlorobenzene was carried out in the absence of an electron donor species at 254 nm in cetyltrimethylammonium bromide surfactant solution. The results are consistent with the excited triplet undergoing homolytic cleavage of a C-Cl bond in competition with formation of the excimer, in which the radical anion undergoes...

  • Bioprospecting the Chemical Diversity of Plant-associated Fungi

    Creator:
    González-Montiel, Gisela Abigail
    Abstract:
    Fungi have long been used for discovery of new chemical scaffolds. In the clinical setting, the fungal natural products penicillin, statins, and cyclosporine have revolutionized medicine to treat diseases and infections. In the environment, fungal natural products have been used as herbicides, fungicides, and insecticides to protect crops, livestock, and...

  • Synthesis and oligomerization of y,4-Diamino-2-oxo-1(2H)-pyrimidinepentanoic acid

    Creator:
    Nelson, Jeffrey Stephen
    Abstract:
    Described herein is the synthesis of an uncharged stereoregular oligonucleotide analog consisting of cytosine bases linked at specific intervals to a polyamide backbone derived from (L)-glutamic acid. Preparation of this analog entailed borane reduction of (L)- pyroglutamic acid to give optically pure lactam alcohol 9. Tosylation and alkylation with cytosine...

  • A Reversible Conversion Cathode – Convert Dual-ion Battery into Rocking-Chair Battery

    Creator:
    Wu, Che-Yu
    Abstract:
    In Dual-ion Batteries, anions as charge carriers might be a potential technique of energy storage. While fluoride anion has been selected as a promising charge carrier for energy storage due to its high charge/mass ratio and small ionic radius, carbonate anion has never been reported as a charge carrier for...

    Creator:
    Ungerer, Carl Andre
    Abstract:
    The atmospheric trace element abundances associated with slash burning have been measured by instrumental neutron activation analysis (INAA). On site ground level samples were collected during the slash burning season using high volume samplers and a cascade impactor. In addition to the air samples, soil, wood and ashed wood samples...

  • Synthesis of polybenzimidazoles containing arylene sulfone and ether linkages

    Creator:
    Cook, Diana Lynn
    Abstract:
    Polybenzimidazoles were synthesized from 3,3'-diaminobenzidine (DAB) and dicarboxylic acids. The polymerizations using the dicarboxylic acid monomers were carried out in polyphosphoric acid (PPA) and phosphorus pentoxide/methansulfonic acid (PPMA) which acted as the solvent and condensing agent. The resulting polybenzimidazoles had inherent viscosities in the range of 0.12 to 0.84 dL/g....
