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.

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...

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 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...

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 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...

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...
