Summary

The kinetics of oxidation of uric acid by thallium(III) has been studied in acetate buffers; the oxidation products are alloxan and urea. Deprotonated uric acid, UaH−, and T1(OAc)3 are the reacting species. A probable reaction mechanism has been proposed conforming with rate law (1)-d[T1III]/dt=(k′1K′1+k′2K′2K1/[H+]) [T1III][UaH2]/1+K4[OAc−] A comparative analysis with other soft acids HgII and PbIV has been attempted.
