摘要：

Annulation should tilt the benzene/Dewar-benzene equilibrium toward benzenes the largest effective annulating ring being six-membered; MP2(fc)/6-31G*//RHF/6-31G* methods are needed to reproduce experimental isomerization energies, but 6-31G calculations suffice td show trends for molecular design. [GRAPHICS] Smaller "n" should favor isomerization; effective rings will have n less than or equal to 6. (C) 1997 Elsevier Science B.V.
