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 ...
Studies of 2,1-benzothiazine, silver-catalyzed rearrangement and 1,5-hydride shift

Probing supramolecular assemblies via fluorescent reporter molecules
(University of Missouri--Columbia, 2007)
the organization of the capsule interior when fluorescent reporter molecules, (1-(9-anthryl)-3-(4-dimethylaniline) propane) and pyrene butyric acid, became entrapped. Solution state spectroscopic data, in agreement with solid state single crystal X...
Investigating reaction conditions for controlling the self-assembly of metal-seamed pyrogallol[4]arene nanocapsules
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Upon coordination to metal ions, C-alkylpyrogallol[4]arenes (PgCn, where n is the number of carbon atoms in the pendant alkyl chains), can be assembled ...
Inactivation of protein tyrosine phosphatases by endogenous and dietary agents
(University of Missouri--Columbia, 2009)
disrupting signaling pathways inside cells. It is possible that these small molecules are exerting their widely reported biological effect by the modification of protein tyrosine phosphatase activity. This information is critical to our understanding...
