The Intensity Of Ligand Absorption, Shing-Bong Chen

Masters Theses & Specialist Projects

The ultraviolet absorption spectra of a number of aryl phosphines and amines and transition metal complexes of triphenylphosphine have been determined. These data indicate that the intensity of the Õ* ¬ Õ phenyl ring transition is not only sensitive to the central atom attached to the ring but is also affected by the metal ion in the complex. Since the degree of covalency depends on the degree of back donation, the oxidation state of the metal ion was found to be the most important factor in determining the intensity of the absorption. The more covalent the metal-phosphine bond, the lower …

Kinetic Properties Of Partially Purified Isocitrate Dehydrogenase, Devji Dedhia

Masters Theses & Specialist Projects

Within the past few years kinetic studies of NADP⁺- specific isocitrate dehydrogenase have been conducted extensively following isolation from bacteria, yeast and vertebrates. However, the kinetic properties of NADP⁺ - specific isocitrate dehydrogenase have not been adequately characterized in filamentous fungi. Therefore, the present study was undertaken to examine the kinetic behavior of partially purified NADP⁺ - specific isocitrate dehydrogenase enzyme isolated from Phycomyces blakesleeanus.

During this study Michaelis constants (Km) and maximum velocities (Vmax) were determined for threo-Ds-isocitrate, NADP⁺, and Mn²⁺ as well as the number of binding sites of these …

The Reactions Of Sodium Naphthalenide With Carbonyl Compounds And Esters, Manhar Vora

Masters Theses & Specialist Projects

The purpose of this investigation was to study the reactions of sodium naphthalenide with various carbonyl and acyl compounds. J. W. Stinnett, Jr. investigated aspects of the reactions of carbonyl compounds and that study was expanded. The major emphasis, however, was to extend the investigation to the reactions of esters. With regard to the reactions of esters, it was thought that sodium naphthalenide might provide a synthetic advantage, as compared to the sodium metal solutions, in the reduction of the acyl compounds to their corresponding acyloins.

The Reduction Of Carbonyl Compounds By Sodium Naphthalenide, James Stinnett

Masters Theses & Specialist Projects

The purpose of this investigation was to study the reactions of sodium naphthaienide with various aromatic carbonyl compounds, particularly aromatic aldehydes and ketones. Although sodium naphthalenide was first investigated in 1936 by Scott et al, the synthetic utility of this alkali metal adduct in organic chemistry has only recently been explored. It was thought that sodium naphthalenide might provide a synthetic advantage, as compared to sodium metal solutions, in the reduction of carbonyl functions to their respective glycols and/or alcohols.

The Attempted Synthesis Of Ethylenimine, Rabindranath Patnaik

Masters Theses & Specialist Projects

The object of this investigation was to study the homogeneously catalyzed reaction of acetylene and ammonia and particularly to attempt to synthesize ethylamine by the reaction of acetylene and ammonia.

Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy

Masters Theses & Specialist Projects

This research was part of a project underway at Barren River and Nolin River Reservoirs in south-central Kentucky. The research was partially supported by a grant through the Sport Fishing Institute, Washington, D.C.

The study reported herein was concerned with the analysis of trace metal concentrations in the two reservoirs. It is believed that the fish population may in part depend upon the trace metals present in the water. It is anticipated that the data presented in this paper will eventually be correlated with the biology studies of the reservoirs being carried out by the Department of Biology of Western …
