The n.'m.r. spectrum (1) of protopine (I) has been assigned on the basis of rapid ring inversion in the ten-membered ring. However, the bands of the methylene protons in that ring are somewhat broader than expected. The broadness of the long-range coupling, but there may also be a contribution inver
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 inve
