## Abstract The radical anions of 5,6‐didehydrobenzocyclooctene (**3**), 5,6,9,10‐tetradehydrobenzocyclooctene (**4**) and 1,4,7,10‐tetramethyl‐5,6‐didehydrodibenzo[__a__, __e__]‐cyclooctene (**6**) were prepared __in situ__ from dibromo‐precursors and have been characterized by ESR and ENDOR spect
The circular dichrokm and electronic spectra of the 2,2'dimethyl-l,l'-binaphthyl anion radical have been studied. The assimments of the complicated absorption bands of :hespecies were made with theaid of the s&s in the circular dichroism spectrum and the dihedral angle of the anion radical was set i
