Abstract

Using HPLC technique, two different pathways were found for the oxidation of bromomalonic acid by Ce4+. One route is dominant when the Ce4+ concentration is low compared to that of bromomalonic acid (BrMA). The end products of this reaction route are bromoethenetricarboxylic acid (BrEETRA), CO2, and Br-. For this route two slightly different mechanisms (both are based on radical-radical recombination reactions) are proposed, which can explain the formation of BrEETRA. The other pathway is dominant when Ce4+ is in excess. This route leads to a complete oxidation of BrMA to CO2. No intermediates of this route were found, however.
