Transparent p-type conducting BaCu₂S₂ films

Creator:: Park, Sangmoon, Keszler, Douglas A., Valencia, Melinda M., Hoffman, Randy L., Bender, Jeffrey P., and Wager, John F.
Abstract:: p-type conducting films of α- BaCu₂S₂ have been deposited onto glass and KBr substrates, yielding a conductivity of 17 S/cm and a Hall mobility of 3.5 cm²/Vs. For a 430-nm-thick film, the optical transparency approaches 90% in the visible portion of the spectrum at 650 nm, and a transparency of...

Decomposition of di-p-toluenesulfonyl-hydrazones

Creator:: Bradway, Diane Elizabeth
Abstract:: Thermal decomposition of several di-p-toluenesulfonylhydrazones was studied. It was found that the carbene decomposition of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone gave two products resulting from rearrangement. One was identified as 2,5-dimethyl-1,3,4-hexatriene. A tentative structure for the second was proposed. During the course of the study, a more convenient procedure for thermal decompositions was...

Magnetic properties of an analog compound for cytochrome P-450

Creator:: McCann, Steven Wayne
Abstract:: This thesis describes a Mossbauer effect and electron paramagnetic resonance study of iron (III) tetraphenylporphyrinatobenzenethiolate benzene thiol, an analog compound for bacterial cytochrome P-450. The compound is unusual in that it provides a model for the two ferric reaction states of cytochrome P-450. The iron in the model compound exhibits...

Studies towards the total syntheses of (+)-phomactins A, D and G

Creator:: Schwartz, Keith D.
Abstract:: Studies towards the total synthesis of (+)-Phomactin A (1), D (6), and G (9), fungal metabolites with unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 354 and 356, which contain all of the carbon atoms of 1, 6 and 9....

Part I: Synthetic studies toward the southern portion of Azaspiracid-1; Part II: Total synthesis of amphidinolide B₁ and the proposed structure of amphidinolide B₂

Creator:: Lu, Liang
Abstract:: The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the synthesis of southern FGHI ring system...

A Diels-Alder approach to biaryl synthesis

Creator:: Ashburn, Bradley O.
Abstract:: An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...

Expanding the scope of a Diels-Alder approach to biaryl synthesis

Creator:: Schwartz, Johanna Perkins
Abstract:: A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted biaryls can be produced in just three to four steps from commercially available materials utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will illustrate the ability of mono...
