In this communication we present electron paramagnetic resonance (EPR) evidence for the formation of the peroxymalonyl radical (MAOO{sup *}) in the aerobic oxidation of malonic acid (MA) by ceric ions. We present results of kinetic investigations on the MAOO{sup *} and the malonyl radical (MA{sup *}) in oxygen saturated solutions. EPR measurements were performed utilizing a Bruker ER200D X-band (9.5 GHz) EPR spectrometer. 14 refs., 2 figs.
