## 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 DielsβAlder reacti
## Abstract Tetradehydrodianthracene (TDDA; 1) reacts with electronrich dienes such as butadiene, cyclopentadiene and __o__βquinodimethane under ambient conditions. Only 1:1 products 5β8 were observed even with a large excess of the diene and under drastic conditions (though two strained and highly
