Nonlinear Dynamics Derived From The Oxyhalogen Oxidation Of Selected Organosulfur Compounds, Edward Chickwana

Dissertations and Theses

Structure, stability, kinetics and mechanisms of oxidation of some physiologically important organosulfur compounds were studied and the results obtained show that oxidation occurs mainly at the reactive sulfur center of the molecules. These results not only display the usual S-oxygenation pathways that have been observed with most thiocarbamides, but also show dimerization and cyclization.

The oxidation of guanylthiourea, GTU, was studied in the presence of mildly acidic iodate and the strong oxidants bromate and bromine. The GTU reaction dynamics with iodate show clock reaction characteristics and oligooscillatory formation of iodine both in excess oxidant and reductant. The major oxidation product …
