Producing Dihydrofurans Using Palladium (Ii) Catalyst And Optimized Base, Chandler Mitchell
Producing Dihydrofurans Using Palladium (Ii) Catalyst And Optimized Base, Chandler Mitchell
Undergraduate Honors Thesis Collection
Dihydrofurans serve as building blocks for other compounds in organic synthesis. The main goal of this project was to discover an efficient and relatively inexpensive pathway for producing monosubstituted dihydrofurans in high yield from cyclic boronic half acids. Aldehydes were converted to homoallylic alcohols by the addition of allylmagnesium bromide. The alcohols were then transformed into cyclic boronic half acids using ringclosing metathesis with Grubbs 1st Generation Catalyst and alkenyl boronic esters. Finally, monosubstituted dihydrofurans were produced using a palladium (II) catalyst with a base. Palladium (II) catalysts that were tested include [1,1'- bis(diphenylphosphino)ferrocene]palladium (II) dichloride, palladium (II) acetate with …
Crossed Product Algebras Over Dihedral Field Extensions, Kaitlyn Lee
Crossed Product Algebras Over Dihedral Field Extensions, Kaitlyn Lee
Undergraduate Honors Thesis Collection
Let F be the field of fractions of R, a ring of power series with coefficients in some field. Let K/F be a finite Galois extension, and assume the integral closure S of R in K is also a power series ring.
In this paper, we consider a construction from ring theory called a crossed product algebra and an associated function f: G × G →K called a cocycle that is used to define a multiplication operation for the crossed product algebra. Consider a crossed product algebra whose cocycle f takes values in S. We give a proof concerning which …
Complexities Of Bi-Colored Rubik's Cubes, Taylor Pieper
Complexities Of Bi-Colored Rubik's Cubes, Taylor Pieper
Undergraduate Honors Thesis Collection
Which of two bi-colored cubes is the simpler puzzle? The differences in the coloring of the cubes creates different symmetries that dramatically reduce the number of states each cube can reach. Which of the symmetries is most reductive? The answer to these questions can be achieved by discovering and comparing the “God’s Number” for these cubes.
Quantitative Analysis Of Acetic Acid In Hard Woods As A Way To Improve Museum Artifact Storage, Alexandria Flora
Quantitative Analysis Of Acetic Acid In Hard Woods As A Way To Improve Museum Artifact Storage, Alexandria Flora
Undergraduate Honors Thesis Collection
Many materials used for storage of museum artifacts have been found to cause damage to the items either through emitting harmful volatile gases or through direct contact. Harmful storage techniques can cause corrosion, discoloration, or deterioration of priceless artifacts. Museum enclosures made of hardwoods have been shown to emit acetic acid vapors that cause damage to the items being stored. In the present study, a review of the effects of acetic acid damage on museum artifacts was performed, and an evolved gas analysis and titration method were used to quantify acetic acid in various hardwoods.
Spectroscopic Analysis Of The Traditional Cyanotype Process And Its Impact On Art, Jacob Applegarth
Spectroscopic Analysis Of The Traditional Cyanotype Process And Its Impact On Art, Jacob Applegarth
Undergraduate Honors Thesis Collection
Reflectance spectroscopy was used to study the cyanotype printing process. Originally this process was used to make photocopies of building designs, but today it is used for art. The cyanotype process is a photo catalyzed oxidation-reduction reaction. This study altered the concentrations and reagents involved in the printing process, and it included the use of ammonium ferricyanide and ammonium iron(III) oxalate along with the traditional potassium ferricyanide and ammonium iron(III) citrate. The impact of these changes on the rate of formation of Prussian blue was observed and quantified. Rate laws and general trends were determined for the reagents involved. Qualitative …
The Role Of Black Hole And Neutron Star Interaction On The Dynamical Evolution Of Dense Stellar Systems, Michael Pajkos
The Role Of Black Hole And Neutron Star Interaction On The Dynamical Evolution Of Dense Stellar Systems, Michael Pajkos
Undergraduate Honors Thesis Collection
With the recent detection of gravitational waves from the Laser Interferometer Gravitational-Wave Observatory, or LIGO, a new realm of gravitational astrophysics has been opened. As the process of observing gravitational wave signals is still in its infancy, there is a need to provide gravitational astronomers with observable signatures in the electromagnetic spectrum. Hence, we explore the impact of solar mass black holes on the morphology of globular clusters. It has long been thought that due to high kick velocities from compact object gravitational interaction, Galactic age Globular Clusters are unable to retain black holes. Recent simulations, however, suggest that a …
Use Of Trispyrazolemethane In The Synthesis Of Organometallic Compounds, Claire Hazelton
Use Of Trispyrazolemethane In The Synthesis Of Organometallic Compounds, Claire Hazelton
Undergraduate Honors Thesis Collection
Trispyrazoleborate is a negatively charged facially coordinating tridentate ligand that has been highly researched and used in many metal complexes. The related ligand trispyrazolemethane has not been widely studied due to its difficult synthesis. The objective of this project is to determine the effects of the neutral nature of the trispyrazolemethane on the metal carbonyl complexes of molybdenum and tungsten. Besides the ligand tricarbonyl complex, iodide and hydride derivatives were synthesized. All compounds were characterized with IR and HNMR.
