The initial rate of carbon monoxide evolution in the reaction of octacarbonyl dicobalt with 2,2,6,6-tetramethylpiperidin-1-oxyl free radical (TEMPO) at 15°C in n-octane solution leading to the 16e complex (TEMPO)Co(CO)2 was found to be first order with respect to the TEMPO concentration, 0.5 order with respect to the Co2(CO)8 concentration, and negative 0.5 order with respect to the CO concentration. Scavenging •Co(CO)4 and •Co(CO)3 by the free radical TEMPO in the rate-determining steps are in accord with the kinetic observation. The observed rate constant is kobs = 6.4 x 10-5 s-1.
