Synthesis Of Aromatic Fluorinated Ketones For Evaluation At The Gaba Receptor, Madeline Griffin
Synthesis Of Aromatic Fluorinated Ketones For Evaluation At The Gaba Receptor, Madeline Griffin
Honors Theses
GABA is a neurotransmitter that inhibits the excitation of neurons. Targeting this specific receptor has the potential to inhibit the central nervous system and possibly treat addiction, anxiety, or mood disorders. Previous research has shown that fluorinated ketones can have valuable applications in the medicinal chemistry of addiction. Some fluorinated ketones have shown activity at the GABA receptor. The main goal of this project was to synthesize aromatic fluorinated ketones for biological evaluation at the GABAB receptor. Another goal was to compare both the monofluorinated and difluorinated analogues synthesized in order to quantify differences in activity from fluorination state. …

Elephant And Anchors ‒ Photoelectron Photoion Coincidence Spectroscopy Of Small Oxygenated Molecules, Apeter Weidner
University of the Pacific Theses and Dissertations
The dissociative photoionization reactions of two small, oxygenated organics, namely 1,3-dioxolane and methyl vinyl ketone, were studied by photoelectron photoion coincidence (PEPICO) spectroscopy. Experiments involving 1,3-dioxolane were carried out in the photon energy range of 9.5‒13.5 eV. The statistical thermodynamics model shows that a total of six dissociation channels are involved in the formation of three fragment ions, namely C3H5O2+ (m/z 73), C2H5O+ (m/z 45) and C2H4O+ (m/z 44), with two channels contributing to the formation of each. By comparing the results of ab initio quantum chemical calculations to the experimentally derived appearance energies of the fragment ions, the most …
