| Abstract: | Depending on the position of the two oxo groups, isomeric dioxo derivatives of benzenoid hydrocarbons drastically differ in the extent and mode of π-electron conjugation. We report here the results of AMI studies of the 14 Kekulean dioxo derivatives of bisanthrene (phenanthro-( 1,10,9,8-o,p,q,r,a]perylene). Our calculations indicate that in this case also the relative stabilities and the geometries of the dioxo derivatives are predominantly determined by π -electron conjugation and to a lesser extent by steric repulsion of the oxo groups in positions 3,4,10 and/or 11 , and by electrostatic repulsion of near-lying oxo groups. |
