(4+3)-cycloaddition chemists of oxidopyridinium ions and related study
(University of Missouri--Columbia, 2019)The (4+3)-cycloaddition reaction is a cycloaddition between a 4-atom species and a 3-atom species to form a seven-membered ring. This reaction results in the formation of seven-membered rings. Our research expanded the ... -
Alkene oxidation by platinum (II) oxo/hydroxo complexes
(University of Missouri--Columbia, 2011)The facile reaction between tetranuclear Pt-oxo complex [(COD)4Pt4([mu]2-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 between ... -
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 ... -
