Cleavage Of Organosiloxanes By Metal Halides, Alvin Joseph Alekna
Cleavage Of Organosiloxanes By Metal Halides, Alvin Joseph Alekna
Honors Theses
The aim of the present research is therefore to investigate the clevage of organosiloxanes by several metal halides that were omitted from consideration in previous experminetal work.
Studies Of Aryl Hypochlorites, Edwards Stengle Atwood
Studies Of Aryl Hypochlorites, Edwards Stengle Atwood
Honors Theses
Of all the reactions of the esters of hypohalous acids, those least documented are the reactions and characteristics of the phenolic esters. This includes the reactions of hypohalites in the presence of a strong Lewis acid, such as aluminum trichloride. Only one reaction has been published in which an organic hypohalite is reacted in the presence of a strong Lewis acid; this dealt with an alkyl hypochlorite. Berman and Lowy (1) reacted tertiary butyl hypochlorite with benzene in the presence of aluminum trichloride, reporting tertiary butylbenzene as the product.
A Study Of The Kolbe Electrolysis Using Mixed Mono-Ethyl Glutarate And Mono-Ethyl Malonate, Richard John Gilbert
A Study Of The Kolbe Electrolysis Using Mixed Mono-Ethyl Glutarate And Mono-Ethyl Malonate, Richard John Gilbert
Honors Theses
The study of electrolytic reactions of organic compounds was first attempted soon after the discovery of the electrolysis if water in 1800. These reactions were not used in synthesis until after 1847 when Kolbe discovered that aliphatic acids. The field has greatly increased since then, and it is now possible to carry out synthesis by electrolytic reduction, oxidation, cathodic coupling, anodic coupling, and substitution. It was the purpose of this work to attempt one mixed Kolbe reaction and analyze its products qualitatively not quantitatively. If time permitted, quantitative analysis would be attempted.
A Study Of Stable Ion-Pairs, James Carlton Garrison
A Study Of Stable Ion-Pairs, James Carlton Garrison
Honors Theses
A study was made of the ion-pair that forms when the commercial surfactant, Ethoquad 18/25, is mixed with azo dyes such as methyl orange or methyl red. The study determined some of the physical characteristics of the ion-pair, and two attempts were made to determine the structure. Through a series of titrations it was found that the ion-pair is sensitive to pH and can be dissociated in strong acid solution. An attempt to determine the structure of the complex by infra-red analysis failed. The equilibrium constants for the Ethoquad and two different dyes were determined. On the basis of the …
A Polarographic Analysis Of The Tetracyanoaurate (Iii) And The Dicyanoaurate (I) Complexes, Richard Joseph Klimowski
A Polarographic Analysis Of The Tetracyanoaurate (Iii) And The Dicyanoaurate (I) Complexes, Richard Joseph Klimowski
Honors Theses
A method for determination of the dicyanoaurate and tetracyanoaurate complexes using polarography has been investigated. Whereas distinct wave forms (current-voltage plots) are obtainable, many interference problems exist. Previous work has been confirmed and new data added. Dicyanoaurate I (Au(CN)2) has been satisfactorily investigated and may be classified as a stable complex. Tetracyanoaurate III (Au(CN)4) has been investigated and must be classified as unstable. This a polarographic method of quantitative analysis for a simultaneous determination of these complexes seems remote.
The Cyclization Of A Diazoketone With Boron Trifluoride Etherate, Stephen Joseph Isser
The Cyclization Of A Diazoketone With Boron Trifluoride Etherate, Stephen Joseph Isser
Honors Theses
Normally, a diazoketone reacts with an acid to form a substituted methyl ketone. When a nucleophilic center is present at an α or β position of R, this reaction may lead to the formation of a cyclic ketone (11). It was the purpose of this research to investigate the cyclization of the aliphatic methoxydiazoketone, 1-diazo-4-methoxy-4-phenyl-2-butanone (I), when treated with BF3 in ether, to give the five-membered ring 5-phenyltetrahydrofuranone-3 (II).
The D O Acidity Function For Aqueous Sodium Hydroxide Solutions, James T. Macgregor
The D O Acidity Function For Aqueous Sodium Hydroxide Solutions, James T. Macgregor
Honors Theses
The H o acidity function developed by Hammett and Deyrup is well known, and values for this function are established for solutions of various acids.
Studies Of The Reactions Of 1-Diazo-3-Methoxy-3-Phenyl-2-Propanone With Boron Trifluoride Etherate, Ross Grant Mackinnon
Studies Of The Reactions Of 1-Diazo-3-Methoxy-3-Phenyl-2-Propanone With Boron Trifluoride Etherate, Ross Grant Mackinnon
Honors Theses
Normally the reaction of diazo ketones wih acids yields straight chain-substituted ketones. The product can be a cyclic compound if within the diazo ketone there lies a nucleophilic center at the α or β position.
The Preparation Of 2-Aryl-3-Methyl-4-Metathiazanones And 2-Aryl-3-Methyl-4-Thiazolidones, John Charles Wilson
The Preparation Of 2-Aryl-3-Methyl-4-Metathiazanones And 2-Aryl-3-Methyl-4-Thiazolidones, John Charles Wilson
Honors Theses
It had been found that 3-mercaptopropanoic acid would react readily with ammonia or primary amines yielding Schiff bases which when reacted aryl aldehydes would give 2 and 2,3 disubstituted 4-metathiazanones. The report included a variety of substituted benzaldehydes, pyridyl and thienyl carboxaldehydes, ammonia, and alkyl and aralkylamines.
Photochemical Reactions Of Benzophenone And Cyclohexene, Michael I. Goldberg
Photochemical Reactions Of Benzophenone And Cyclohexene, Michael I. Goldberg
Honors Theses
Aldehydes and ketones absorb weakly in the 290 mμ region of the ultraviolet spectrum, and also at 200 mμ (this wavelength region being analogous to that occurring in the spectra of olefinic compounds). This weak absorption band in the carbonyl absorption spectrum can be attributed to an n → π* transmission of a non-bonding electron on the oxygen atom to an anti-bonding π orbital in the multiple bond to give a singlet state. It is this absorption and consequent formation of an energized state which appears responsible for most of the photochemical transformation of saturated ketones in condensed (liquid) phases. …
Kinetic Study Of The Autocatalytic" Photodeboronation Of Benzeneboronic Acid In Phosphoric Acid Media, Bradley C. Bockrath
Kinetic Study Of The Autocatalytic" Photodeboronation Of Benzeneboronic Acid In Phosphoric Acid Media, Bradley C. Bockrath
Honors Theses
Kinetic studies are often valuable in the investigation of reaction mechanisms. They can reveal the molecularity of a reaction and perhaps give an indication of possible intermediate steps. Comparisons of rate studies, such as kinetic isotope effects, can indicate the rate determining step of a reaction. Finally, rate studies can reveal when changes in reaction mechanism accompany changes in one or more kinetically significant variables. This study investigates the possibility of a new or altered reaction mechanism as one kinetic variable is changed. The reaction of interest is the hydrolysis of benzeneboronic acid in concentrated phosphoric acid media.
