Abstract
The tetraphenylene radical anion (2˙–) generated by Na, K and Cs reduction in tetrahydrofuran and 2-methyltetrahydrofuran has been investigated by EPR/ENDOR spectroscopy. The results clearly establish that the decrease of the molecular symmetry of 2˙– from D2d to C2v detected upon exhaustive reduction arises from ion-pair formation. This finding unequivocally rules out the assumption stated in previous papers that the EPR spectra mirroring the lower symmetry originate in a bis(biphenylene)-like geometry of 2˙–.Keywords
