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...

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 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...

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...
