(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The scope of [2,3]-sigmatropic rearrangement of propargylic sulfinates to allenic sulfones by silver catalysis was expanded. A series of new propargylic ... -
Alkene oxidation by platinum (II) oxo/hydroxo complexes
(University of Missouri--Columbia, 2011)The facile reaction between tetranuclear Pt-‐oxo complex [(COD)4Pt4(μ2-‐O)2Cl2]2[BF4]2 (1) and norbornene (NB) yields the stable platinaoxetane [(COD)2Pt2(OC7H10)Cl][BF4] (2) in quantitative yield. A rapid reaction ... -
Alkene-oxo and alkene-alkene coupling on Pt(II)
(University of Missouri--Columbia, 2005)Tetranuclear Pt(II) oxo-complex [(COD)4Pt4([mu]3-O)2Cl2](BF4)2 (1) (COD = 1,5- cyclooctadiene) was found to readily react with a variety of alkenes (ethylene, norbornene, propylene and cyclopentene). The most significant ... -
Ammonia elimination from protonated nucleobases
(University of Missouri--Columbia, 2007)The dediazoniations of the diazonium ion 1 of 4-aminopyrimidine and of the tautomeric cytosinediazonium ions 2 and 3 are facile and result in the formations of cations 4, 5, and 6. The pyrimidine ring-opening of 4, 5 and ... -
Anion and solvent influences on the self-assembly of copper(I) coordination solids
(University of Missouri--Columbia, 2005)The investigation of solvent and anion influences on the self-assembly of copper(I) coordination solids are presented. As these extended solids vary in structural design as reactions conditions are varied, both those ... -
Anisotropic energy transport properties of 1,3,5-Triamino-2,4,6-Trinitrobenzene (TATB)
(University of Missouri--Columbia, 2016)Anisotropic energy transport properties were determined theoretically for crystals of the insensitive explosive 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) using molecular dynamics simulations. Determination of these ... -

(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Anisotropic organic materials are attracting increasing interesting for their highly electro-optic characteristics. We are especially interested in ... -
Applications of elemental analysis for archaeometric studies: analytical and statistical methods for understanding geochemical trends in ceramics, ochre and obsidian
(University of Missouri--Columbia, 2006)Three areas are covered in this dissertation: elemental analysis of Caborn-Welborn ceramics, elemental analysis and geochemical characterization of ochres, and construction and implementation of a portable XRF instrument ... -
Applications of radiotracer in plant biology
(University of Missouri--Columbia, 2013)A radioactive tracer (radiotracer) is generally defined as a radioactive isotope that is used as a tracer, which can be followed or tracked within a system of interest. The use of radiotracers involves the substitution of ... -
Arsenic for potential diagnostic imaging and radiotherapy
(University of Missouri--Columbia, 2015)Targeted agents hold promise for non-invasive in vivo imaging, therapy, and monitoring of diseases. Foundational work focused on imaging and therapy of cancer has centered primarily on the use of 18F, 90Y, 99mTc, and 131I ... -
