  • Carbene rearrangements : intramolecular interaction of a triple bond with a carbene center

    Creator:
    Dan̄ino, José C.
    Abstract:
    The tosylhydrazones of 2-heptanone, 4,4-dimethy1-2- heptanone, 6-heptyn-2-one and 4,4-dimethy1-6-heptyn-2- one were synthesized and decomposed under a variety of reaction conditions: dry lithium and sodium salt pyrolyses, sodium methoxide thermolyses in diglyme and photolyses of the lithium salt in tetrahydrofuran. The saturated analogues 2-heptanone tosylhydrazone and its 4,4-dimethyl isomer afforded the...

  • A study of the chemistry of diisopropyl-, cyclopropylisopropyl-, and dicyclopropylcarbene

    Creator:
    Wuerch, Stephen E.
    Abstract:
    The effect of the conjugation with cyclopropyl rings on the activation parameters for the formation of carbenes from the corresponding diazo compounds was investigated using diisopropylcarbene (46), cyclopropyl-isopropylcarbene (47), and dicyclopropylcarbene (48). Each of these three carbenes was generated by the thermolysis of the parent benzenesulfonylhydrazone potassium salts using DMSO...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • 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...

  • The photochemistry of some O-(methylcarbamoyl) oximes

    Creator:
    McCarthy, Kermit D.
    Abstract:
    The photochemistry of aldicarb and two related compounds, 0-(methylcarbamoyl) isobutyraldehyde oxime and 0-(methylcarbamoyl) trimethylacetaldehyde oxime was explored under laboratory conditions. Upon irradiation aldicarb decomposed rapidly to methylamine, dimethylamine, tetramethylsuccinonitrile, and 1-methylthio-2, 3-dicyano-2, 3-dimethylbutane. The other two compounds decomposed only after a long period of irradiation. The difference in reactivity was...

  • Carbene chemistry : I. Stereochemical integrity at Cα in ketone tosylhydrazones : II. Hydrogen migration in 2-carbena-6, 6-dimethylnorbornane

    Creator:
    Balyeat, John Robert
    Abstract:
    The tosylhydrazones of exo-3-deuteriocamphor and 2- deuterio-2,4-dimethy1-3-pentanone were treated with Nbromosuccinimide (NBS) and pyruvic acid to regenerate the parent ketones. The ketones from the pyruvic acid cleavage show a significant loss of deuterium. The ketones from the NBS cleavage show no loss of deuterium, indicating that stereochemical integrity at.

  • Photochemistry of some bromoarenes

    Creator:
    Jang, Jung-suk
    Abstract:
    The photodebromination of selected bromoarenes has been studied at 300 nm to determine the the possible mechanistic pathways leading to product. Irradiation of 4-bromobiphenyl (BpBr) at this wavelength leads to the product biphenyl. The quantum yield of intersystem crossing (0.98) and quenching studies with cis-1 ,3-pentadiene suggest that the reaction...

  • The photochemistry of some insect juvenile hormone analogs

    Creator:
    Siggel, Lorenz
    Abstract:
    The photochemistry of some analogs of insect growth regulators (IGR's) was studied. Methyl geranate, TY, was synthesized and the mechanisms of its photochemical reaction pathways were studied by a variety of techniques. Direct irradiation of 71 in ether leads to the formation of five new products: 98, the product of...
