Abstract
The cw resonance Raman spectra of the products of electrochemical oxid ation of 4-(N,N-dialkylamino)biphenyl compounds, with alkyl = methyl, methyl-d3 or ethyl, are analyzed and compared with the time-resolved r esonance Raman spectra of the photogenerated radical cation of these a mines. The anodic oxidation is shown to lead to the formation of the r espective N,N,N',N'-tetraalkylbenzidine radical cation and dication, a nd a mechanism scheme for the oxidation is proposed.
