Interactions of organic S-nitroso and C-nitroso compounds with metalloporphyrins.
(2002)
Chapter 4 of this dissertation deals with the first isolable nitrone adducts of metalloporphyrins. Thus, the metalloporphyrin nitrone complexes (OEP)M(CO)(DMPO) (M = Ru, Os; DMPO = 5,5-dimethyl-1-pyrroline N-oxide) were ...
Synthesis of nitrogen heterocycles via transition metal catalyzed reductive cyclizations of nitroaromatics.
(2003)
This research focuses on applying a catalyst system discovered in this laboratory, for the intermolecular allylic amination of alkenes with nitrobenzenes, to the synthesis of nitrogen heterocycles via an intramolecular ...
A study of the interactions of nitric oxide and nitric oxide containing molecules with heme proteins.
(2006)
The interactions of nitric oxide (NO), nitrite and organic nitroso compounds with heme proteins are biologically relevant. The formation of adducts between these NO-containing species and myoglobin (Mb) has served as a ...
Studies of the complexation reactions of polyether ionophore antibiotics monensin A and lasalocid A with lead(II), zinc, calcium and sodium cations.
(2000)
Lead-ionophore complexes of the form PbLX and PbL2 (L = monensin A or lasalocid A; X- = anion) were isolated and characterized by elemental analysis (X = Cl--) and ESI-MS (X = Cl --, NO3, CH3COO--). Changes in the UV-Vis ...
From nitrite reductase to Alzheimer's disease: Design, synthesis, and reactivity of new nitrogen-, oxygen-, and sulfur-containing ligands and their copper complexes.
(2006)
Transition metal ions are essential for a wide range of biochemical transformations and are found in more than one half of all known enzymes. Our interest in the bioinorganic chemistry of copper prompted us to develop new ...
Interactions of nitric oxide and nitrosamines with group 8 metalloporphyrins.
(2007)
Chapter 1 of this dissertation introduces the importance of nitric oxide in biological systems.
Synthesis, structure, and solution properties of benzoannelated cryptands.
(2006)
Cryptands An2.2.1 and An2.2.2 were synthesized by high dilution techniques. Attempts to produce An3.1.1 gave primarily the 2 + 2 addition product An3.1.1.3. X-ray crystallography, ESI-MS, and NMR techniques were used to ...
Investigation of ligand misdirection using the kinetic element effect and the kinetic enthalpy effect.
(2000)
Metal complexes were synthesized with the atropisomeric dabp. X-ray crystal structures were solved for [Ru(bipy)2(dabp)]2+ and [(eta6-C6H6)Ru(dabp)(Cl)]+. Only one diastereomer was observed for [Ru(bipy)2(dabp)] 2+ in the ...
Tuning the frontier orbital character of iron-thiolate complexes.
(2000)
Another part of this work describes the solvatochromatic effect of CpFe(CO) 2(SC6H5) dissolved in different solvents. A blue shift in the UV-vis spectra occurs as CpFe(CO)2(SC6H 5) is solvated in more polar solvents, which ...
Mechanisms of electrophilic aromatic substitution reactions of (eta('6)-arene)molybdenum(phosphine)(, 3) complexes.
(2000)
The mechanism of protonation of (eta6-C6H 6)Mo(TRIPOD) (1) (TRIPOD = tris(1,1,1-diphenylphosphinoethyl)methyl ethane) to give [(eta6-C6H6)MoH(TRIPOD)] + was reported to involve a cyclohexadienyl intermediate. In this ...
