1.4- Diethylpyrazine radical cation iodide

Pyrazine (367) was converted into 1,4-diethylpyrazinediium bis(tetrafluorobo-rate) (368), the 1,4-diethylpyrazine radical cation iodide (369, X = I) (electrolytic reduction Nal J,), and finally the corresponding tetraphenylborate (369, X = BPh4) (NaBPh4 18%) which was sufficiently stable for elemental and X-ray analysis.548...
