Synthesis and reactivity of osmium-chromium oxidation catalysts and routes to a chiral analog
… osmium center, followed by proton transfer and $\beta$-hydrogen elimination of the products yields a reduced osmium-chromium complex. This reduced complex can react with dioxygen to form a bridging peroxo complex that can react with a molecule of the reduced complex to regenerate two equivalents …

Development of new transition metal-catalyzed carbon-fluorine, carbon-nitrogen, and carbon-carbon bond forming processes
… studies. The preference of conducting [beta]-hydrogen elimination rather than reductive elimination from the trans-LPd(vinyl)F complex, which is generated predominantly due to the trans-effect, caused the poor regioselectivity of the fluorination reaction under TESCF₃-free conditions. An …

Low-temperature protonation studies of an electron-poor osmium methyl complex, and molecular precursors for the construction of graphene nanostructues with atomically precise edge structures
… (dfmpm) by addition of ethereal hydrogen chloride. Treatment of (C5Me5)2Os2Br4 with excess dfmpm in the presence of zinc dust in refluxing ethanol gave the piano stool osmium complex (C5Me5)Os(dfmpm)Br, which was converted to (C5Me5)Os(dfmpm)Me in excellent yield by treatment with …

Investigations into cyclopropanation and ethylene polymerization via salicylaldiminato copper (II) complexes
Two distinct overall research objectives are in this Master’s thesis. Very little relates the two chapters apart from the ligands. The first chapter addresses diastereoselective homogeneous copper catalyzed cyclopropanation reactions. Cyclopropanation of styrene and ethyl diazoacetate (EDA) is a …
