Abstract

The oxidation of N,N-dimethylaniline by alkaline hexacyanoferrate(
III), at constant ionic strength, gave N-methylformanilide. The rate of the reaction was dependent on the first powers of the' concentrations of substrate and oxidant, but was independent of the concentration of alkali in the range studied (0.01 M to 0.10 M). The mechanistic pathway involved an electron abstraction from the amine, giving a radical intermediate which was detected by ESR spectroscopy as a three-line spectrum with a peak height
of 1 : 2 : 1.
