Atmospheric trace element abundances associated with slash burning

Creator:: Ungerer, Carl Andre
Abstract:: The atmospheric trace element abundances associated with slash burning have been measured by instrumental neutron activation analysis (INAA). On site ground level samples were collected during the slash burning season using high volume samplers and a cascade impactor. In addition to the air samples, soil, wood and ashed wood samples...

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...

A stereochemically controlled approach to the morphine alkaloids: racemization of 8,9-benzo-4,5-dihydro-6,7-pyrido[4,3-d] oxanin-3(2H)-ones

Creator:: Runyan, Mark T.
Abstract:: A method for the control of absolute stereochemistry in morphine syntheses has been demonstrated by the resolution and efficient racemization of the advanced morphine precursor , 9-methoxy-3-methyl-5,6-dihydro-3H-benzofuro[3,2-e]isoquinoline- 7(7aH)-one, I. This was accomplished by the facile coversion of optically resolved I to its ring opened form, 5,6,7,8-tetrahydro-10-methoxy-3-methyl-7-oxo[1]benzoxonino[ 6,7-c]pyridinium tosylate, II, (Equation...

Design, construction and application of an instrument for simultaneous measurement of molecular fluorescence, absorbance and chemiluminescence

Creator:: Yappert, Marta Cecilia
Abstract:: An instrument was constructed to measure molecular fluorescence (FL) or chemiluminescence (CL) and absorbance (ABS) simultaneously. The lower, middle, and upper portions of the test solution are probed to obtain ABS, FL, and CL data. Optical fibers are used extensively. The ABS and FL or CL spectra are acquired in...

A reaction rate determination of aluminum with a microcomputer-based spectrofluorometer

Creator:: Campi, Gregory Louis
Abstract:: The development and optimization of a fluorometric reaction rate method for the determination of aluminum is described. Modifications to existing instrumentation permit automatic monitoring and reporting of measurement conditions. Automatic correction of measured analytical signals is provided if monitored parameters deviate from optimum values. A computer controlled standard addition procedure...

The determination of gasoline and alkyl benzenes in aqueous solution and the development of a remote reaction chamber for fiber optic remote sensing

Creator:: Waddle, Robert D.
Abstract:: The development and optimization of a single-phase derivatization technique for small ring aromatics in water are presented. Also described are the design, optimization and application of a remote reaction chamber for fiber optic sensing. Aqueous solutions of the major aromatic compounds in gasoline are derivatized to o-nitrosophenol-Cu complexes with a...

Synthetic transformations of shikimic acid

Creator:: White, Edward D., III
Abstract:: Four strategies which involve synthetic elaboration of the shikimate nucleus are discussed. Methyl shikimate was differentially protected as the 3,4-0-cyclopentylidene ketal and as the 5- 0- tert- butyldiphenylsilyl ether. The methyl ester was then reduced with diisobutylaluminum hydride and the resulting allylic alcohol was oxidized to aldehyde 47 with pyridinium...
