摘要：
In this lecture, an account is presented of new methodology which permits quantitative assessment of ring inversion and bond shifting barriers within [8]annulene derivatives. With optically active cyclooctatetraenes in hand, it suffices to determine the overall racemization rate and to obtain independent experimental measurement of one additional rate constant for complete numerical definition of their dynamic parameters. The antiaromatic nature of planar delocalized cyclooctatetraenes is analyzed and compared in magnitude to the overall conformational energetics of these systems.
