Graduate Theses, Dissertations, and Problem Reports (ETD)

Structure, stability, kinetics and mechanisms of oxidation of some important organosulfur compounds (2-aminoethanethiolsulfuric acid, 4-methyl-3-thiosemicarbazide and thionicotinamide) have been investigated by using UV-VIS, NMR, stopped-flow, and qualitative analysis. Results obtained showed that oxidation occurs mainly at the reactive sulfur center of the molecules via successive addition of oxygen atoms. The oxidation of thionicotinamide, an important xenobiotic, gave different oxygenated products, depending on the oxidizing power of the oxidant used. The sulfinic acid of thionicotinamide is stable with mild oxidizing agents while stronger oxidants desulfurize the molecule to yield sulfate as observed with other organosulfur compounds studied. Mechanism of oxidation leading …
