(17) LH Píette, P. Ludwig and RN Adams, ibid., 83, 3909 (1961). to the presence of dimethylanilino free radical ions. At high pH indications are one or more radical ion species develop which change with time of electrolysis. The interpretation of the hyperfine interactions of these spectra are con-sistent with the presence of the tetramethyl-benzidine positive ion. Full interpretation of the epr results must await further study, but it is safe to conclude that the results are consistent with the idea that the initial charge transfer does not produce dimethylanilino radicals, or if it does, the lifetime of this species is too short to be de-tected by standard electrochemistry or epr spectroscopy under the conditions employed herein. Summary.—By a variety of electrochemical and supporting techniques, the oxidation of,-dimethylaniline at pH 2-3 has been shown to lead to,,','-tetramethylbenzÍdine and its oxi-dized quinoid form as principal products.
