A series of pyrene-based polycyclic aromatic compounds, indeno[cd]pyrene, diindeno[cd,fg]pyrene, diindeno[cd,jk]pyrene, tris-(tert-butylindeno[cd,fg,jk])pyrene, and tetrakis-(tert-butylindeno[cd,fg,jk,mn])pyrene, were reduced with alkali metals in [D8]tetrahydrofuran, and the resulting anions were studied by NMR spectroscopy. It was found that the diatropic character of the dianions obtained de...
