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 ...
Studies on the nucleophilic substitution reactions of a dimeric cyclopentadienone

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nucleophilic substitution reactions of 3,5-Dibromo-3a,4,7,7a-tetrahydro-4,7-methano-indene-1,8-dione (48) have been studied. Amines, thiols and alcohols ...
Design and construction of multicomponent spheroidal assemblies on the nano-scale via the self-assembly approach
(University of Missouri--Columbia, 2006)
reported within the literature use metal-ions as the directing influence in ligand assembly (i.e. without the metal-ions, the ligands would not assemble into spheroidal structures). However the C-alkylpyrogallol[4]arene molecules can assemble into hexameric...
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 ...
