Abstract:

Tetrakis-p-dimethylaminophenyl ethylene I was shaken with AgNO3 in water for 12 hr to produce two dinitrate derivative II addition of KI to II in water produced two diiodide derivative III, brilliant green crystals precipitated from water. Water solutions of II and III showed no E.P.R. signal. In ethylene chloride there was a marked difference between the optical and E.P.R. spectra of II and III. Solutions of II were purple and showed no radical activity solutions of III were green ang gave an intense E.P.R. signal, corresponding to at least 20 of the material being a free radical. The optical and E.P.R. spectra are the same whether III is dissolved in ethylene chloride or iodine is added to I in ethylene chloride.
