Synthesis And Study Of Novel Quinoxaline Di-N-Oxide And 3-Acyl-2-Methylquinoxaline Di-N-Oxides, Cyprian Okwara Ogbu
Synthesis And Study Of Novel Quinoxaline Di-N-Oxide And 3-Acyl-2-Methylquinoxaline Di-N-Oxides, Cyprian Okwara Ogbu
Masters Theses
This research project consists of two parts. The first involved the synthesis of a novel quininoxaline di-N-oxide via benzofuroxan. The second part was the use of this compound as a synthetic precursor.
It was assumed that 3,4-dimethylaniline would be successfully converted to 5,6-dimethybenzofurazan 1-oxide (5,6-dimethybenzofuroxan) through a sequence of reaction steps. Fortunately, this assumption was correct as the desired compound was produced. This compound was utilized in synthesizing the novel 3-acetyl-2,6,7-trimethylquinoxaline 1,4-dioxide. From the structure of this adduct, it is believed that it will take part in condensation reactions associated with methyl ketones without disrupting the quinoxaline di-N-oxide framework, and …
Synthesis And Reactions Of A-Diketones And Preparation Of Some New Benzimidazoles, Mohamad Reza Agharahimi
Synthesis And Reactions Of A-Diketones And Preparation Of Some New Benzimidazoles, Mohamad Reza Agharahimi
Masters Theses
This report will discuss the synthesis of 2,5-dl-(p-chlorophenyl)-3,4-dioxoadiponitrile and its reactions. This compound exists in the form of 4,4'- dichloropulvinic nitrile which is a precursor to 4,4'-dichk>rovulpinic acid. These compounds have been shown to have antiinflammatory activity in rats.
The benzimidazole and pyridazine derivatives of 4,4'-dichioropulvinic nitrile and the benzimidazole derivative of 4,4'-dichk>rovuipinic acid are another group of compounds that are also believed to have useful biological activities. The Pinner synthesis of imidates is used to make the intermediate to the benzimidazole derivative of 4,4'-dichloropulvinic nitrile.
This report will include the methodology of the reactions and …
A Synthetic Approach To Novel Heterocyclic Herbicides, Paul Antony Pathadan
A Synthetic Approach To Novel Heterocyclic Herbicides, Paul Antony Pathadan
Masters Theses
The purpose of this research study was to prepare novel heterocyclic herbicides. The first phase of the project was to synthesize 1-(nitromethyl)-4-phthalazone.
In the second phase 1 - (nitromethyl)-4-phthalazone was treated with 1,3-propane-dithio-di-p-toluene sulfonate in presence of sodium hydride to get the target compound 4-(1'-nitro-l,3-dithiane)phthalazone.
It is believed that this compound might block the electron transport system of aerobic cells1 . So further investigation of this compound may lead to novel herbicides.

Synthesis Of Pyridine Nucleosides By Cycloaddition Reactions And Synthesis And Condensation Reactions Of 4-Aryl-2-Oxytetronimides, Glenn L. Heise
Masters Theses
Experiment 1: The reaction of various glutaconaldehyde salts (Na+ or K+) with glycosyl isothiocyanates has resulted in the formation of a novel class of compounds. Relatively mild conditions were utilized for the synthesis which occurs in four steps, and in good yield, starting from glucpseptentaacetate. These reactions were found to be regiospecific. The unique physical and spectral properties of the model compound 1-(2,3,4,6-tetra-0-acetyl-β-D-glycopranosyl)-2-thiono-3-pyridine carboxaldehyde are also discussed.
Experiement 2: Early synthetic methodologies have recently been utilized in the synthesis of 4-aryl-2-oxytetronimides. These compounds have been found to participate in condensation reactions with various substituted o-phenylene diamines. A …
Reactivity Of Some Nitrogen-Containing Compounds At Supercritical Water Conditions, David M. Tiffany
Reactivity Of Some Nitrogen-Containing Compounds At Supercritical Water Conditions, David M. Tiffany
Masters Theses
The use of water at cuperctirical conditions to remove nitrogen from several nitrogen-containing compounds was studied with the purpose of exploring the use of supercritical water as a method of removing nitrogen from the extraction products of coal. Quinoline and isoquinolone were the primary model compounds used with benzonitrile and carbazole also being examined briefly. Reaction conditions varied in temperature (350-500°C), pressure (3500-5200 psi), and water density (0.170-.0.426g/cc). The major products formed by isoquinoline were benzene, toluene, ethylbenzene, and o-xylene as well as nonvolatile tar and char. Quinoline produced aniline and toluidine in addition to those obtained from isoquinoline. Most …

Cationic And Anionic Micellar Catalyzed Hydrolysis Of Hydroxamic Acids, Douglas Eugene Conran
Cationic And Anionic Micellar Catalyzed Hydrolysis Of Hydroxamic Acids, Douglas Eugene Conran
Masters Theses
The hydrolysis of octanohydroxamic and N-methyloctanohydroxamic acids in the presence of cationic and anionic micelles was investigated. Rate constants were determined for the hydrolyses in cetyltrimethylammonium bromide (ctab), the cationic surfactant, with 0.1111 N NaOH and in sodium 1-dodecanesulfonate, the anionic surfactant, with 0.09270 N HC1 at 50.01 + 0.11°C. The acid hydrolysis and the base hydrolysis of N-methyloctanobydroxamic acid followed the standard model for micellar catalysis.
The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada
The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada
Masters Theses
The dianions of phenylacetone and its para-substituted derivatives were generated using potassium hydride and n-butyl lithium in tetrahydrofuran. Methyl, ethyl, and n-butyl iodides were used to alkylate the dianions. The results of alkulation indicated that C1 is preferentially attacked by the less active ethyl and n-butyl iodides. The results further show that terminal alkylation is enhanced by electron-donating groups at the para-position of the phenyl ring. The results are rationalized in terms of the difference in electron density at C1 and at C3 in the dianion, on the basis of resonance theory. The regio-selectivity of alkylation as …

Studies In Syntheses Of Non-Isoprenoid Sesquiterpenes, Raojibhai Javerbhai Patel
Masters Theses
The purpose of this study was to find the shortest route to prepare the 1,9-dimethyl decalone system I, a key intermediate in the synthesis of non-isoprenoid sesquiterpenes. The decalone system I was prepared in good yield by dehydrating the hydroxyketone II with 50% H2SO4. The dehydration of hydroxyketone II was also affected by heating in the presence of iodine crystals to yield 80% of the decalone system I.
The basic kinds of approaches under investigation were the Diels-Alder reaction and the Robinson annellation. The Diels-Alder reaction between the conjugated diene, 1-acetoxybutadiene (III) and 2,3-dimethylcyclohexenone (IV) under …
