“…In 1969, a one-electron reduction of an N -trimethylsilyl-substituted p -phenylenediamine to a radical anion was established by means of EPR, , where the success in reducing an electron-rich molecule was explained in terms of a distortion of the n N /π-delocalization due to a twisting of the bulky (Me 3 Si) 2 N groups around the bond between the N and the ring C atom . Further examples are the formation of radical anions of substituted o -phenylenediamine upon treatment with diphenylthallium hydroxide or reaction with alkali-metal mirrors combined with irradiation . Angulo et al published their work on a spectroscopic characterization of tetracyano- p -phenylenediamine, which, although containing the p -phenylenediamine moiety, due to the substitution with four cyano groups becomes a strong oxidant and can be regarded as a tetracyanobenzene rather than as a p -phenylenediamine derivative …”
