## Abstract Theoretical calculations and simple MO considerations predict that a coplanar and spatially close arrangement of double bonds in structures such as tetradehydrodianthracene 1, should both lower the LUMO and raise the HOMO energy of the Ο€ system. Thus the reactivity in Diels‐Alder reacti
