5-diene using potassium in dimeth-oxyethane proceeds in two steps: firstly, the acquisition of one electron yields the unstable radical anion [FB(MeCCMe)2BF]·–, isoelectronic with durosemiquinone; and secondly the potassium film removes the fluorine substituents and the radical anion [B(MeC-CMe)2B]·– is produced which is stable at room temperature and represents a novel heterocycle, tetramethyl-1,4-diborine
