The Road Less Traveled: New Chemistry Of Old Reactive Intermediates, Erin Carcella Mclaughlin
The Road Less Traveled: New Chemistry Of Old Reactive Intermediates, Erin Carcella Mclaughlin
Master's Theses and Capstones
Conditions were optimized to utilize benzyl alcohol and acetate substrates in Friedel-Crafts electrophilic aromatic substitution reactions. Anhydrous iron (III) chloride (20 mol%) was shown to be an efficient catalyst when using benzene in a microwave reactor. Rapid reactions and minimal further purification make this procedure suitable for chemical library generation. We attempted to develop a synthetic route to the little known intermediate, ortho-xylallene. Though work to date has been unsuccessful, we have determined that traditional routes via allene formation may be viable. Rearrangements of terphenyls, phenyl-naphthalene, and 1,1'-binaphthalene by ipso-arenium cations were studied using triflic acid in 1,2-dichloroethane. Preferred formation …
Detection Of Trehalose In Porphyra Extracts Using Mass Spectrometry And Gas Chromatography-Mass Spectrometry, Ying Huo
Master's Theses and Capstones
It is known that trehalose helps many plants to survive under desiccated environment26. This property of trehalose has also been proposed to explain why Porphyra could survive desiccation when left on dry land for a long period of time25. However, after extensive study25, effort at identifying trehalose in Porphyra has been unsuccessful, leaving the question of whether trehalose really exists in Porphyra unanswered. In my thesis research, in collaboration with Dr. Anita Klein, I set out to use ion-trap mass spectrometry and gas chromatography coupled with mass spectrometry to identify and quantify the amount of trehalose in Porphyra extracts. Using …
