Abstract

Chapter 2 is based on the synthesis and study of the compounds of the bidentate ligand ((5-phenyl-1H-pyrazol-3-yl)methyl)phosphine oxide with molybdenum and cobalt as the transition metal. The complexes were analyzed via FTIR, NMR, UV-Vis, Fluorescence Spectroscopy, TGA, DFT, and XRD. Chapter 3 resulted in the synthesis of the complexes [Ni(II)SSRRL](PF6)2 and [Ni(II)SRSRL](Cl)(PF6) of which [Ni(II)SRSRL](Cl)(PF6) had not been previously analyzed. Both products were analyzed via FTIR, NMR, UV-Vis, CV, DFT, and XRD. Chapter 5 contains the results of the characterization and modification of 4 natural zeolites (AZLB-Na, AZLB-Ca, NM-CA, NV-Na) from the United States in an attempt to increase the surface area of the zeolites to make them more efficient at the adsorption/absorption of lead from a simulated contaminated water source. AZLB-Na and AZLB-Ca turned into amorphous material, while NV-Na and NM-Ca retained crystallinity when treated with concentrated hydrochloric acid. NV-Na and NM-Ca untreated had surface areas of 19.0(4)m2/g and 20.0(1)m2/g, respectively. After 30 minutes of reflux in concentrated hydrochloric acid, the surface area increased to 158(7)m2/g and 111(4)m2/g, respectively. The study based on the uptake of lead showed NV-Na and NM-Ca removing 1.50(17)meq/g Pb2+ and 0.27(14)meq/g Pb2+ and with the treated zeolites 30 min HCl NV-Na and 30 min HCl NM-Ca resulting in 0.41(23)meq/g Pb2+ and 0.09(9)meq/g Pb2+. Chapter 6 relates to the epoxidation of olefins. In the case of cyclohexene with 5 mole percent t-butyl hydroperoxide, a yield of 2(1)% cyclohexene oxide, 8.0(3)% 2-cyclohexen-1-ol, and 23.66(1)% 2-cyclohexen-1-one was achieved with no catalysts, and in the epoxidation of cyclooctene using 5 mole percent t-butyl hydroperoxide, a yield of 40(2)% cyclooctene oxide, 1.18(2)% 2-cycloocten-1-one, and 0.35(1)% 2-cyclooctene-1-ol was achieved with no catalysts.
