Synthesis and oligomerization of y,4-Diamino-2-oxo-1(2H)-pyrimidinepentanoic acid

Creator:: Nelson, Jeffrey Stephen
Abstract:: Described herein is the synthesis of an uncharged stereoregular oligonucleotide analog consisting of cytosine bases linked at specific intervals to a polyamide backbone derived from (L)-glutamic acid. Preparation of this analog entailed borane reduction of (L)- pyroglutamic acid to give optically pure lactam alcohol 9. Tosylation and alkylation with cytosine...

Synthesis of substituted cyclooctatetraenide dianions ; Cycloheptadienyl complexes of the ḏ- and f̲-transistion elements ; Reactions of cyclohexanone with metal vapors

Creator:: Miller, Jeffrey Templeton
Abstract:: I. Lithium alkyl and aryl monosubstituted cyclooctatetraenide dianions (Li₂ C₈H₇-R; R = methyl, n- butyl, sec- butyl, tert- butyl, phenyl and benzyl) were synthesized by the reaction of the appropriate organolithium reagent with cyclooctatetraene in diethyl ether or tetrahydrofuran. The reaction occurred cleanly and with good yield of lithium monosubstituted...

High-resolution X-ray photoelectron spectroscopy of CO₂ and other small molecules

Creator:: Hahne, Jeffrey A.
Abstract:: The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...

High resolution spectroscopic studies of ³²S¹⁶O₃ and ³⁴S¹⁶O₃

Creator:: Barber, Jeffrey
Abstract:: The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...

Chiral synthesis of alcohols via asymmetric epoxidation

Creator:: Engebrecht, Jeffrey Ronald
Abstract:: Enantioselective epoxidation of crotyl alcohol, followed by a cuprate mediated methylation, gave a 1:1 mixture of (2S) -3- methyl -1,2- butanediol and (2R,3S)-2-methy1-1,3- butanediol. The latter was separated as its 2,4,6-trimethylbenzenesulfonate derivative and converted via the iodide to the corresponding phosphonium salt. The separated butanediol derivatives were independently transformed to...

Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

Creator:: Park, Cheol-Hee
Abstract:: New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...

Determination of fluorinated alkyl substances in aqueous systems

Creator:: Schultz, Melissa M.
Abstract:: Fluorinated alkyl substances, which can be persistent, toxic, and bioaccumulative, have been quantitated in many densely populated and remote regions, including in air, surface waters, groundwater, and biota; however, little is known about their transport or behavior in the environment. Wastewater effluent is one of the principal routes for introducing...

A photoactivable microfluidic device for heavy metal ion extraction

Creator:: Nammoonnoy, Jintana
Abstract:: The development of microfluidic devices for heavy metal extraction is presented in this dissertation. Various research areas, covering subjects from photochromic compound syntheses to microchip fabrication techniques are explored to develop microfluidic devices capable of extracting heavy metal ions from drinking water. Through integration of the beneficial characteristics of both...
