The kinetics of oxidation of N,N-dimethylformamide by chromium(VI) has been studied spectrophotometrically in aqueous perchloric acid media at 20ΠC. The rate showed a first-order dependence on both [Cr(VI)] and [DMF], and increased markedly with increasing [H Ο© ]. The order with respect to [HClO 4 ]

β¦ Synopsis
The equations necessary for the determination of the rate constants corresponding to the opposite elementary steps for formation of the oxidant-reductant ester intermediate, as well as that corresponding to its redox decomposition, in the reduction of chromiumWI) by glutathione and other thiols at physiological pH have been deduced. It is shown that those three rate constants can be obtained with a good reproducibility.
