摘要

I 2 3 identical conditions, dihydrobullvalene is not.'Qualitative theory provides a simple explanation. The CloHlo dianion (2) is expected to be stabilized, because it is a mode (2, 0, 0) longicyclic.'The CloHl, dianion (3) is expected to be destabilized (Le., bishomo antiaromatic), because it is an 8-a-electron pericyclic3 The value of such predictions has increasingly been questioned in recent years, 4 and particularly as it applies to anion~.~~" ...
