Chemistry Faculty Publications

The title compound, C₁₆H₁₂N₄O₈, was prepared by the photochemical reaction of 9-methyl­anthracene and tetra­nitro­methane in dichloromethane. Intermolecula face-to-face π–π stacking inter­actions are present along the a axis.

Structural And Chiroptical Properties Of The Two Coordination Isomers Of Ybdota-Type Complexes, Lorenzo Di Bari, Gennaro Pescitelli, A. Dean Sherry, Mark Woods

Chemistry Faculty Publications and Presentations

Studies of the structural, physical, and chemical properties of the lanthanide(III) complexes of DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) and related ligands are often complicated by the presence of two coordination isomers in solution. Since these coordination isomers are in exchange and cannot be separated, many techniques offer information only on the weighted average of the two isomers. Lanthanide ion complexes formed with the ligands S(RRRR)NO₂BnDOTMA and S(SSSS)NO₂BnDOTMA preferentially adopt only one of the two common coordination isomers in solution, so the ytterbium complexes of these ligands offer a unique opportunity to study …

Possible Side Reactions Due To Water In Emulsion Polymerization By Late Transition Metal Complexes. 1. Water Complexation And Hydrolysis Of The Growing Chain, Iordan H. Hristov, Roger L. Dekock, Grant D. W. Anderson, Inigo Göttker-Schnetmann

University Faculty Publications and Creative Works

The transition metal catalyzed ethylene polymerization in aqueous emulsion has been increasingly successful in the last couple of years. Water however adversely affects the polymerization process by (a) competing with ethylene for the binding site at the metal and (b) hydrolyzing the growing chain. Neutral salicylaldiminato and cationic diimine complexes of Ni and Pd with different substituent patterns are studied here by density functional theory to determine their propensity toward water complexation and hydrolysis of the growing chain. Experimental NMR studies have also been carried out on the protonolysis of the Ni(II)-based Grubbs catalyst. It is found that in general …

Synthesis Of Novel Alkaline Earth Metal Acetylides, Eva Baker

Renée Crown University Honors Thesis Projects - All

Acetylide complexes of the heavy alkaline-earth metals were first introduced by our group. With our group being interested in how the ligand and donor affect the structural chemistry of the resulting complexes, my project was focused on the detailed analysis of past work and the extension towards new ligand and donor sets. The work required the analysis and development of synthetic procedures towards these highly reactive species.

Past synthetic work in our group had established several synthetic routes towards the target compounds including transamination and toluene elimination. Using toluene elimination, I was able to reproduce the synthesis of M(C≡CSiPh_{3 …}

Synthesis, Structural Studies And Desilylation Reactions Of Some N-2-(Trimethylsilyl)Ethyl-N-Nitrosocarbamates, Arpitha Thakkalapally, Vladimir Benin

Chemistry Faculty Publications

The present report describes the preparation and characterization of several N-2-(trimethylsilyl)ethyl-N-nitrosocarbamates, designed as precursors to thermally unstable secondary N-nitrosocarbamate anions via fluoride-assisted cleavage. X-ray structural studies demonstrate that the core N-nitrosocarbamate moiety has a nearly planar geometry, with an s-E orientation at the N–N bond. DFT calculations (B3LYP/6-31+G(d)) reproduce accurately the structural features of the title compounds and detailed conformational analysis at the same level of theory addresses the long-standing issue of preferred geometries for three classes of related structures: N-nitrosocarbamates, N-nitrosoureas and N-nitrosoamides. Desilylation studies demonstrate that both the …

Synthesis Of Nanomaterials: Magnesium Hydroxide Nanoparticles And Applications For The Catalyzed Decomposition Of Toxins, Travis Witte

Presidential Scholars Theses (1990 – 2006)

Utilizing a modified sol-gel process, a series of Mg(OH)2 nanoparticles will be produced. Each series synthesized will utilize six different toluene/methanol solvent ratios to yield six samples of nanoparticles. each with a different surface area. The surface area is expected to increase as the toluene/methanol ratio is increased. After preparation is completed, the nanoparticles will be characterized by BET method nitrogen adsorption measurement, IR spectroscopy and thermal gravimetric analysis. The Mg(OH)2 will then be utilized in a simple photocatalysis experiment to determine its possible use as catalyst for the degradation of toxic substances.
