Synthesis And Selected Reactions Of [Pi]-(Arene) Chromium Tricarbonyls, Anthony L. Scaggs
Synthesis And Selected Reactions Of [Pi]-(Arene) Chromium Tricarbonyls, Anthony L. Scaggs
Master's Theses
This project was concerned wit hthe preparation of two pi-(arene)-chromium tricarbonyl compounds that could serve as a synthetic intermediates to more complex systems. These intermediates would be particularly well-suited for the preparation of mono-complexed diaryl compounds. The two intermediates selected were pi-(acetophenone) chromium tricarbonyl and pi-(benzyl bromide) chromium tricarbonyl. After the intermediates had been synthesized, their utility in several selected reactions was to be examined.
Aromatic Solvent Induced Shifts Of Trifluoromethyl Pyrazoles, Manuel Constantine Bourlas
Aromatic Solvent Induced Shifts Of Trifluoromethyl Pyrazoles, Manuel Constantine Bourlas
Master's Theses
Nuclear Magnetic Resonance (NMR) has been used to study the keto-enol equilibrium in a number of trifluoromethyl S-diketones as well as the dihydropyrazoles obtained when these S- diketones are reacted with thiosemicarbazide. The technique of Aromatic Solvent-Induced Shifts (ASIS) has been used to study the geometry of the collision complex and the strength of the association between solute and solvent. From the data presented, the stereochemistry of these pyrazoles has been determined and a reaction mechanism for their formation has been proposed.
Ferroxidase-Ii: A Blood Serum Lipo-Protein, Christine Shih Ming Sung
Ferroxidase-Ii: A Blood Serum Lipo-Protein, Christine Shih Ming Sung
Master's Theses
Ferroxidase-II was definitely identified as a lipoprotein. Cholesterol and phospholipids remained tightly associated with the ferroxidase-II protein following extensive purification. Quantitative analysis showed that it is a high-density lipoprotein. Thin-layer chromatographic analyses indicated that phosphatidylcholine accounts for the majority of the bound phospholipid with lysophosphatidyl choline and sphingomyel in accounting for the remaining phospholipid.
Treatment of purified ferroxidase-II with phospholipase C or A resulted in a loss of ferroxidase activity which paralleled the hydrolysis of phospholipid. Phospholipid D treatment also resulted in the loss of ferroxidase activity, yet the loss was not as great as with other phospholipases. A lipid-depleted …
