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...

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...

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...

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...

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...
