The attempted generation of the potentially aromatic6,7-diphenyldibenzo[e,g][1,4]diazocine dianion from sodium in THF leads with profound rearrangement to the isomeric N-(2-amino-1,2-diphenylethenyl)carbazole dianions and, after hydrolysis, to a 55:45 mixture of Z- and E-isomers of N-(2-amino-1,2-diphenylethenyl)carbazoles. These isomers were separated and their individual structures determined by
