The Preparation And Kinetics Of Sterically Hindered Gold (Iii) Complexes, David Luther Fant
The Preparation And Kinetics Of Sterically Hindered Gold (Iii) Complexes, David Luther Fant
Honors Theses
The purpose of this research was to prepare and study complexes with steric hindrance greater than that of the dien complex but less than that of the Et4dien complex.
Some Aspects Of Quantum Mechanics In Chemical Theory, Thomas Freeman Babson
Some Aspects Of Quantum Mechanics In Chemical Theory, Thomas Freeman Babson
Honors Theses
The physics of microscopic phenomena is called quantum mechanics. When quantum mechanics is extended to the macroscopic scale, the classical macroscopic physics results. Atomic interactions such as the formation of bonds between atoms falls into the range of physics described by quantum mechanics. Because of the interest of a chemist in such interatomic effects, it seems reasonable that a chemist would be interested in quantum mechanics because it is the physics governing these effects. The point of this thesis is to present some of those aspects of quantum mechanics that are directly applicable to molecular systems and that can aid …
The Developement [Sic] Of Phosphorometric, Fluorometric And Absorption Analyses For The Measurement Of Carbamates And Carbamic Acids As An Explanation Of Carbon Dioxide Transport In Blood, Edward Theodore Gray
The Developement [Sic] Of Phosphorometric, Fluorometric And Absorption Analyses For The Measurement Of Carbamates And Carbamic Acids As An Explanation Of Carbon Dioxide Transport In Blood, Edward Theodore Gray
Honors Theses
Phosphorometric, flourometric, and absorption analyses have been developed for the measurement of amino acids, carbamic acids, and carbamates. The absorption analysis may be done in any solvent while the other two methods are limited to non-re-emitting solvents. Water is not excluded in any of the analyses. A carbamate or carbamic acid can be detected even in the presence of amino acids as low as 0.5%, with an overall accuracy of ± 0.3)%. Tentative assignments have been made for the n, π* direct triplet excitation bands for the carbonyls of glycine and its carbamic acid, acetyl chloride, ethyl acetate, and acetamide. …
Synthetic Approaches To Certain Acenapthalene Drivatives, Douglas Jeffrey Binder
Synthetic Approaches To Certain Acenapthalene Drivatives, Douglas Jeffrey Binder
Honors Theses
The purpose of this investigation is the synthesis of bis- acenaphth- (1, 2a)- acenaphthene. The experimental procedures used generally follow those of previous workers. The use of 1, 8- dibromonaphthalene is necessary throughout the synthesis. The preparation used follows that of letsinger, after a preferred synthesis of 8- bromo- 1- naphthotic acid. The latter compound reacted via a modified Hunsdiecker reaction to yield 1, 8- dibromo- naphthalene. Other approaches tried never seemed to result in improved yields, or were successful. Besides this approach to 1, 8- dibromonaphthalene, an attempt to circumvent its need has been made by running a dilute …
1-3 Dipolar Cycloadditions Of Nitrile Ylides, Steven Paul Braff
1-3 Dipolar Cycloadditions Of Nitrile Ylides, Steven Paul Braff
Honors Theses
1-3 dipolar cycloaddition is the union of a 1-3 dipole, a-b-c, with a system containing a multiple bond, d-e, to form a five membered ring. In this scheme, center c contains an electron sextet, and concommitant positive charge, while center c contains an unshared pair of electrons and is the anionic center of the dipole. In the cycloaddition reaction, the 1-3 dipole and the multiple bond system (called the dipolarophile), collapse to form a five membered ring with loss of all formal charges. All together, eighteen 1-3 dipolar systems have been mentioned. The synthetic potential with respect to heterocyclic adducts …
Cationic Copolymerization Of B-Pinene And Styrene, Charles Peter Snyder
Cationic Copolymerization Of B-Pinene And Styrene, Charles Peter Snyder
Honors Theses
Cationic polymerizations are the least understood of all polymerization reactions. Perhaps even less understood are copolymerizations using cationic catalysts. Very little can be found in the literature concerning B-pinene and styrene copolymers. This work was done to shed some light on this interesting subject.
Attempted Synthesis Of Diethyl 7-Dimethylsilabicyclo 2.2.1 Hepta-2,5-Dione-1,4-Dioate, David Kenneth Tart
Attempted Synthesis Of Diethyl 7-Dimethylsilabicyclo 2.2.1 Hepta-2,5-Dione-1,4-Dioate, David Kenneth Tart
Honors Theses
An attempt was made to synthesize diethyl 7-dimethylsilabicyclo [2.2.1) hepta-2,5-dione-l,4-dioate by reacting dimethyldichlorosilane with the dianion of 1,4-dicarbethoxy- 2,5-cyclohexadione. The products formed in the reaction were silicones and 0-silylated polymeric materials. If any of the desired product was formed, it was not detected.
Synthesis Of C14-Labeled Bis (P-Chlorophenyl) Acetic Acid (Dda), William Michael Silver
Synthesis Of C14-Labeled Bis (P-Chlorophenyl) Acetic Acid (Dda), William Michael Silver
Honors Theses
The past three decade has seen the widespread use of DDT as an insecticide. As a persistent insecticide, its use has prompted a great amount of research into the fate of DDT in living organisms. A large number of metabolites of DDT has been found and many identified, although not all of the metabolites were found in all of the experimental bacterium, insects, or mammals.
Photochemical Solvolysis Of Optically Active 3,5-Dimethoxy-Α-D-Benzyl Acetate, Peter Jerry Frank
Photochemical Solvolysis Of Optically Active 3,5-Dimethoxy-Α-D-Benzyl Acetate, Peter Jerry Frank
Honors Theses
The purpose of this work was the stereochemical study of the photochemical solvolytic reaction of 3,5-dimethoxybenzoic acid, optically active 3,5-dimethoxy-α-d-benzyl alcohol was prepared. The specific rotation of the alcohol was compared to the alcohol produced from the photochemical solvolytic reaction of 3,5-dimethoxy-α-d-benzyl acetate.
