Turkish Journal of Chemistry
The kinetics of oxidation of ethylenediaminetetraacetic acid (EDTA) by N-bromosuccinimide (NBS) in aqueous alkaline media was investigated at 25°C. Analysis of the results showed the reaction is first -- order with respect to [NBS] and apparently less than unit order each with respect to [EDTA] and [alkali]. The influence of the reaction products, ionic strength, temperature effect and dielectric constant of the medium on the rate of reaction was studied. The proposed mechanism is consistent with the observed kinetics. The reaction constants involved in the mechanism were derived. There is a good agreement between the observed and calculated rate constants …

Honors Theses
The structural beauty and interesting bonding properties of polycyclic cage compounds have been a source of fascination to many chemists. In this work, progress toward the synthesis of large oxabowl systems, such as hexaoxa[6]peristylane and its derivative dipbenylhexaoxa[6)peristylane, is described. Thus, the adduct obtained from the cycloaddition of maleic anhydride and cyc!ooctatetraene is converted into key dicarbonyl intermediates. Subsequently, the ozonolysis of these intermediates is carried out in order to generate hexaoxa(6)peristylane as well as diphenylhexaoxa[6]peristylane. Molecular modeling studies, performed at the semi-empirical level, are also described.
