✦ Synopsis

The energy barriers to ring inversion of 3,5,7-cyclooctatrienone (I) (11, and ~i~-l,2-dibromo-3,5,jr-cyclooctatriene (II) (2) have been determined by proton magnetic resonance (pmr) spectroscopy. We wish to report that the parent compound, 1,3,5-cyclooctatriene (III)*, has an appreciably lower inversion barrier.
