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...

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.

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...

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...
