Synthesis Of Alkyl Aryl Ethers Using A Halogen Exchange Coupled To An Ullmann Etherification, Antonio Campedelli Jun 2020

Synthesis Of Alkyl Aryl Ethers Using A Halogen Exchange Coupled To An Ullmann Etherification, Antonio Campedelli

Honors Theses

The Ullmann ether synthesis is a reaction that couples aryl halides to aliphatic alcohols. It works best with aryl iodides because the aryl bromides are much less reactive, and aryl chlorides are even more so. A Finkelstein type halogen exchange reaction has been shown to effectively substitute iodide for bromide on aryl bromides with high yields. The goal of this project is to develop a one pot halogen exchange, Ullmann coupling reaction to allow for aryl bromides to be coupled successfully to aliphatic alcohols. This is feasible because the reaction conditions of the two reactions are so similar. Several condition …

Development Of Catalytic Chromia-Based Aerogels, Fiona Fitzgerald

Honors Theses

Over one billion automobiles are in use around the world, the majority of which employ internal combustion engines. Catalytic converters are used to convert the toxic compounds found in car exhaust -- carbon monoxide, nitrogen oxides (NOx) and hydrocarbons -- to less harmful gases. The typical catalytic converter employs as catalysts expensive raw materials (platinum, palladium and/or rhodium) wash-coated onto an alumina-based ceramic substrate. Aerogel materials have high surface area and thermal stability, properties that make them attractive for catalysis applications. Aerogels made with transition metal oxides are candidates to replace platinum in the catalytic converter. Chromium oxide (chromia) materials …


Gama-Lactams And The Reformatsky Reaction: New Tricks For Old Chemistry, Dylan Dupont Jun 2020

DUPONT, DYLAN. An Alternative Synthetic Pathway to γ-Lactam Compounds

Through the Application of Novel Reformatsky-Type Chemistry. Department

of Chemistry, June 2020

ADVISOR: James C. Adrian Jr. Ph.D.

It is the intent of the present report to relate the results of our attempt to elucidate and optimize a novel preparation of γ-lactam compounds. To achieve this end, it is proposed that the use of novel Reformatsky-type chemistry may provide a viable means. Generally, it has herein been validated that employment of α-amino ketones in traditional Reformatsky chemistry will form the traditional Reformatsky ester-adduct, and that this adduct is capable of spontaneously …
