✦ Synopsis

I,IO,I'I'-Tetramethyl-p-phanylenediamine (I) is lmowu to uudergo oue-electron oxidation under a variety of codlltions (2) to the corresponding cation-radical, a blue substauce, which has absorption maxima at 621 IU~ and 571 my (3) The e.e.r. derivative spectrum of the cation-radical of I hae been exteueively Qxuoinsd, (4)

and the hyperflne coupling couetautr have been found to be q I 6.99 gauss, acp3 = 6.76 gauss, a& ah = 1.97 gauee.

We wish to report here the aualogoue(5) one-electron oxidation of the kcouu dithiohydroquinone dimethylether (II).(~)
